Title: REFRESH OF DATA STORED IN A CROSS-POINT NON-VOLATILE MEMORY
Abstract:
Embodiments including systems, methods, and apparatuses associated with refreshing memory cells are disclosed herein. In embodiments, a memory controller may be configured to perform a read operation on one or more memory cells in a cross-point non-volatile memory such as a phase change memory (PCM). The one or more memory cells may have voltage values respectively set to a first threshold voltage or a second threshold voltage. Based on the read, the memory controller may identify the memory cells in the cross-point non-volatile memory that are set to the second threshold voltage, and refresh the voltage values of those cells without altering the voltage values of the memory cells in the cross-point non-volatile memory that are set to the first threshold voltage. Other embodiments may be described or claimed.
