The 8-transistor storage cell provides separate ports for read and write operations, including differential read bit lines. Prior to each read operation, the differential read bit lines are precharged to the low voltage level. During read operations, one of the two differential read bit lines is pulled high towards a high voltage level while the complementary bit line remains at the low voltage level resulting from the precharge. The difference in voltage between the differential read bit lines is sensed to determine the value stored in each 8-transistor SRAM storage cell and complete the read operation. | 2014-04-10 |
20140098597 | SINGLE-ENDED VOLATILE MEMORY ACCESS - A memory includes an array of memory cells that form rows and columns. The rows include memory cell pairs. The memory cells may include two cross-coupled inverters and two pass-devices that couple to alternate sides of the cross-coupled inverters. For a read operation, a wordline drive circuit selects one memory cell of the pair, the selected memory cell being an addressed memory cell while the remaining cell is an unaddressed memory cell. In response to a wordline enable signal, a pass gate in the addressed memory cell couples the addressed memory cell via a complement bitline to an evaluation gate that resolves the data from the read operation. During the read operation, the unaddressed memory cell couples via another pass gate to a true bitline that terminates without an evaluation gate to conserve energy. | 2014-04-10 |
20140098598 | MEMORY CELL ARRAY LATCHUP PREVENTION - A current-limiting device may be configured to be placed along a power-supply bus to limit current through a first complimentary-metal-oxide semiconductor (CMOS) circuit coupled to the power-supply bus so that current does not exceed a trigger current level of a pnpn diode in a second CMOS circuit coupled to the power bus. | 2014-04-10 |
20140098599 | SEMICONDUCTOR MEMORY DEVICE WITH DATA PATH OPTION FUNCTION - A semiconductor memory device may include a memory cell, a bit line connected to the memory cell, a bit line data latch circuit configured to sense-amplify data stored in the memory cell connected to the bit line and to store write data in the memory cell via the bit line; an input/output driver configured to output read data on the bit line to an external device or to drive the write data provided from the external device; and a selection unit configured to select whether the read data and the write data are communicated between the input/output driver and the memory cell with or without use of the bit line data latch circuit. | 2014-04-10 |
20140098600 | SEMICONDUCTOR MEMORY DEVICE HAVING DISCRIMINARY READ AND WRITE OPERATIONS ACCORDING TO TEMPERATURE - A semiconductor memory device is provided which includes a memory cell array including magnetic memory cells arranged in a matrix form of rows and columns and connected with bit lines and a source line; and a temperature sensing unit configured to generate a temperature sensing signal by sensing a temperature of the memory cell array. A memory controller, constituting a memory system together with the semiconductor memory device, may control read and write operations of the semiconductor memory device differently according to the temperature sensing signal of the temperature sensing unit. | 2014-04-10 |
