Abstract

A method and apparatus suspend a program operation in a nonvolatile writeable memory. The nonvolatile writeable memory includes a memory array, a command register, and memory array control circuitry. The command register decodes a program suspend command and provides a suspend signal as an output. The memory array control circuitry is coupled to receive the suspend signal from the command register. The memory array control circuitry performs a program operation in which data is written to the memory array. The memory array control circuitry suspends the program operation upon receiving the suspend signal.
