METHODS, DEVICES AND SYSTEMS USING OVER-RESET STATE IN A MEMORY CELL

摘要

Memory cells, devices and methods are disclosed, including those that involve applying a waveform to a resistive memory cell to program the memory cell to an over-reset state representing a logic value.

主权项

1. A system comprising:
an array of resistive memory cells; and a controller coupled to the array, the controller being configured to apply different single waveforms to memory cells of the array of resistive memory cells to program the memory cells to correspondingly different ones of a plurality of over-reset states, wherein each of the plurality of over-reset states represents a distinct logic value of a plurality of logic values.
