NON-VOLATILE MEMORY SYSTEM OR SUB-SYSTEM

Systems, devices, and methods related to non-volatile memory are described. A non-volatile memory array may be employed as a main memory array for a system on a chip (SoC) or processor. A controller may interface between the non-volatile memory array and the SoC or processor using a protocol agnostic to characteristics of non-volatile memory operation including different page sizes or access time requirements, etc. A virtual memory bank at the controller may be employed to facilitate operations between the SoC or processor and the non-volatile memory array. The controller may be coupled with a buffer to facilitate rapid data operation, and the controller may be configured to selectively access data at the non-volatile array to account for data stored in the virtual memory bank or the buffer. The controller, the virtual memory bank, and the buffer may be configured on one chip separate from the SoC or processor.
