Abstract: A system and technique is disclosed for writing data in a cross-point memory. The state of one or more memory cells of the cross-point memory are sensed and then are continued to be selected and left on. It is then determined which of the one or more memory cells are to change state based on incoming user data that is to be written into the one or more memory cells. The one or more memory cells determined to change state and are still selected to be on are then written by applying a write-current pulse to the memory cells. In one exemplary embodiment, the one or more memory cells comprise one or more phase-change-type memory cell devices.

Abstract: Phase change material can be set with a multistage set process. Set control logic can heat a phase change semiconductor material (PM) to a first temperature for a first period of time. The first temperature is configured to promote nucleation of a crystalline state of the PM. The control logic can increase the temperature to a second temperature for a second period of time. The second temperature is configured to promote crystal growth within the PM. The nucleation and growth of the crystal set the PM to the crystalline state. The multistage ramping up of the temperature can improve the efficiency of the set process relative to traditional approaches.

Abstract: A flash memory device may include two or more flash memory cells organized as a NAND string in a block of flash memory cells, and flash cells, coupled to the NAND string at opposite ends, to function as select gates. The flash memory device may be capable of providing information related to a voltage threshold of the select gates to a flash controller, erasing the flash cells that function as select gates in response to a select gate erase command, and programming the flash cells that function as select gates in response to a select gate program command. A flash controller may be coupled to the flash memory device, and is capable of sending the select gate erase commend to the flash memory device if the information provided by the flash memory device indicates that the voltage threshold of at least one of the select gates is above a predetermined voltage level, and sending the select gate program command to the flash memory device if the information provided by the flash memory device indicates that the voltage threshold of at least one of the select gates is outside of a predetermined voltage range.

Abstract: Examples may include techniques to mitigate errors during a read operation to a memory cell of a memory array. Examples include selecting the memory cell and applying one of multiple demarcation read voltages for respective multiple time intervals to sense a state of a resistive storage element of the memory cell. Examples also include applying a bias voltage to the memory cell following a sense interval to mitigate read disturb to the resistive storage element incurred while the one of the multiple demarcation read voltages was applied to the memory cell.
