Abstract:
1. A method for write operation emulation on embedded non-Flash non-volatile memory without using a Flash erase operation, comprising: receiving a write command, the write command including write data and at least one write address; and writing the write data, starting at the at least one write address, to one or more of a plurality of vertically configured re-writeable non-volatile memory arrays, each memory array is embedded in one of a plurality of vertically stacked memory planes, wherein writing the write data occurs without performing an erase operation before the writing, and wherein the plurality of vertically stacked memory planes are in contact with one another and integrally fabricated directly above a silicon semiconductor substrate including circuitry fabricated on the silicon semiconductor substrate, at least a portion of the circuitry is electrically coupled with the plurality of vertically configured re-writeable non-volatile memory arrays and is operative to perform the writing.
