Abstract
A nonvolatile memory includes a memory array and a control circuit having a command latch and a command decoder. The control circuit receives an output enable signal and a write enable signal to control memory operations of the memory array in accordance with a command latched into the command latch via the command decoder. A write protection circuit is also provided that disables the command latch and the command decoder when the output and write enable signals are both active. The protection circuit includes a pulse generator that generates a reset signal to reset the command latch to the read array state and a control logic that causes the pulse generator to assert the reset signal when an output enable signal and a write enable signal of the memory are both active until after the write enable signal has been forced internally inactive and the command latch closed.
