In some examples, performing a write operation on a memory cell having different voltage polarities across the memory call may allow such a write operation to be completed in a shorter time than a write operation having a voltage of a single polarity. | 2019-10-10 |
20190311769 | Content Addressable Memory Device Having Electrically Floating Body Transistor - A content addressable memory cell includes a first floating body transistor and a second floating body transistor. The first floating body transistor and the second floating body transistor are electrically connected in series through a common node. The first floating body transistor and the second floating body transistor store complementary data. | 2019-10-10 |
20190311770 | NON-VOLATILE STORAGE SYSTEM WITH ADJUSTABLE SELECT GATES AS A FUNCTION OF TEMPERATURE - A non-volatile storage system comprises memory cells arranged in groups of memory cells that include programmable select gates and one or more control circuits in communication with the memory cells. The one or more control circuits configured to identify a select gate that needs to be programmed and program the select gate identified to be programmed if a temperature at the non-volatile memory cells is greater than a minimum temperature and defer programming of the select gate identified to be programmed until the temperature at the non-volatile memory cells is greater than the minimum temperature. In some embodiments, the one or more control circuits are configured to perform dummy memory operations on the plurality of non-volatile memory cells to raise the temperature of the non-volatile memory cells in response to determining that the temperature at the non-volatile memory cells is not high enough. | 2019-10-10 |
20190311771 | POWER SHAPING AND PEAK POWER REDUCTION BY DATA TRANSFER THROTTLING - An arrangement is described used to throttle data in a connected computer device having a device configured to transmit and receive data from a host, the device comprising, a device controller configured to interact with at least memory array and a data transfer throttling arrangement, the data transfer throttling arrangement configured to measure a bandwidth threshold for the device controller and pass data through the device controller when a bandwidth of the device controller is one of at and below a threshold. | 2019-10-10 |
