20140264836 | SYSTEM-IN-PACKAGE WITH INTERPOSER PITCH ADAPTER - An integrated circuit package is disclosed that includes a first-pitch die and a second-pitch die. The second-pitch die interconnects to the second-pitch substrate through second-pitch substrates. The first-pitch die interconnects through first-pitch interconnects to an interposer adapter. The pitch of the first-pitch interconnects is too fine for the second-pitch substrate. But the interposer adapter interconnects through second-pitch interconnects to the second-pitch substrate and includes through substrate vias so that I/O signaling between the first-pitch die and the second-pitch die can be conducted through the second-pitch substrate and through the through substrate vias in the interposer adapter. | 09-18-2014 |
20150067234 | UNIFIED MEMORY CONTROLLER FOR HETEROGENEOUS MEMORY ON A MULTI-CHIP PACKAGE - An enhanced multi chip package (eMCP) is provided including a unified memory controller. The UMC is configured to manage different types of memory, such as NAND flash memory and DRAM on the eMCP. The UMC provides storage memory management, DRAM management, DRAM accessibility for storage memory management, and storage memory accessibility for DRAM management. The UMC also facilitates direct data copying from DRAM to storage memory and vice versa. The direct copying may be initiated by the UMC without interaction from a host, or may be initiated by a host. | 03-05-2015 |
20150186267 | METHOD AND APPARATUS FOR DRAM SPATIAL COALESCING WITHIN A SINGLE CHANNEL - Aspects include computing devices, systems, and methods for reorganizing the storage of data in memory to energize less than all of the memory devices of a memory module for read or write transactions. The memory devices may be connected to individual select lines such that a re-order logic may determine the memory devices to energize for a transaction according to a re-ordered memory map. The re-order logic may re-order memory addresses such that memory address provided by a processor for a transaction are converted to the re-ordered memory address according to the re-ordered memory map without the processor having to change its memory address scheme. The re-ordered memory map may provide for reduced energy consumption by the memory devices, or a balance of energy consumption and performance speed for latency tolerant processes. | 07-02-2015 |
20150194197 | DYNAMIC RANDOM ACCESS MEMORY (DRAM) BACKCHANNEL COMMUNICATION SYSTEMS AND METHODS - Dynamic random access memory (DRAM) backchannel communication systems and methods are disclosed. In one aspect, a backchannel communication system allows a DRAM to communicate error correction information and refresh alert information to a System on a Chip (SoC), applications processor (AP), or other memory controller. | 07-09-2015 |
20150194959 | METHOD AND APPARATUS FOR SELECTIVELY TERMINATING SIGNALS ON A BIDIRECTIONAL BUS BASED ON BUS SPEED - A method of controlling signal termination includes providing first logic for selectively terminating signals received at a first device on a bidirectional data bus, providing second logic for selectively terminating signals received at a second device on the bidirectional data bus, sending first signals from the first device to the second device on the bidirectional data bus at a first speed, stopping the sending of the first signals, after stopping the sending of the first signals, enabling the second logic and shifting a reference voltage of the second device from a first level to a second level, after enabling the second logic at the second device, sending second signals from the first device to the second device on the bidirectional data bus at a higher speed, and controlling the first logic based on a speed of signals received at the first device on the bidirectional data bus. | 07-09-2015 |
20150213849 | PROVIDING MEMORY TRAINING OF DYNAMIC RANDOM ACCESS MEMORY (DRAM) SYSTEMS USING PORT-TO-PORT LOOPBACKS, AND RELATED METHODS, SYSTEMS, AND APPARATUSES - Providing memory training of dynamic random access memory (DRAM) systems using port-to-port loopbacks, and related methods, systems, and apparatuses are disclosed. In one aspect, a first port within a DRAM system is coupled to a second port via a loopback connection. A training signal is sent to the first port from a System-on-Chip (SoC), and passed to the second port through the loopback connection. The training signal is then returned to the SoC, where it may be examined by a closed-loop training engine of the SoC. A training result corresponding to a hardware parameter may be recorded, and the process may be repeated until an optimal result for the hardware parameter is achieved at the closed-loop training engine. By using a port-to-port loopback configuration, the DRAM system parameters regarding timing, power, and other parameters associated with the DRAM system may be trained more quickly and with lower boot memory usage. | 07-30-2015 |
20150213850 | SERIAL DATA TRANSMISSION FOR DYNAMIC RANDOM ACCESS MEMORY (DRAM) INTERFACES - Serial data transmission for dynamic random access memory (DRAM) interfaces is disclosed. Instead of the parallel data transmission that gives rise to skew concerns, exemplary aspects of the present disclosure transmit the bits of a word serially over a single lane of the bus. Because the bus is a high speed bus, even though the bits come in one after another (i.e., serially), the time between arrival of the first bit and arrival of the last bit of the word is still relatively short. Likewise, because the bits arrive serially, skew between bits becomes irrelevant. The bits are aggregated within a given amount of time and loaded into the memory array. | 07-30-2015 |
20150242213 | SYSTEM AND METHOD FOR MODIFICATION OF CODED INSTRUCTIONS IN READ-ONLY MEMORY USING ONE-TIME PROGRAMMABLE MEMORY - Various embodiments of methods and systems for flexible read only memory (“ROM”) storage of coded instructions in a portable computing device (“PCD”) are disclosed. Because certain instructions and/or data associated with a primary boot loader (“PBL”) may be defective or in need of modification after manufacture of a mask ROM component, embodiments of flexible ROM storage (“FRS”) systems and methods use a closely coupled one-time programmable (“OTP”) memory component to store modified instructions and/or data. Advantageously, because the OTP memory component may be manufactured “blank” and programmed at a later time, modifications to code and/or data stored in an unchangeable mask ROM may be accomplished via pointers in fuses of a security controller that branch the request to the OTP and bypass the mask ROM. | 08-27-2015 |
20150243373 | KERNEL MASKING OF DRAM DEFECTS - Systems, methods, and computer programs are disclosed for kernel masking dynamic random access memory (DRAM) defects. One such method comprises: detecting and correcting a single-bit error associated with a physical address in a dynamic random access memory (DRAM); receiving error data associated with the physical address from the DRAM; storing the received error data in a failed address table located in a non-volatile memory; and retiring a kernel page corresponding to the physical address if a number of errors associated with the physical address exceeds an error count threshold. | 08-27-2015 |
