ABSTRACT:
A status register in a non-volatile semiconductor memory is described. The status register outputs to pins of the non-volatile semiconductor memory a number of signals that indicate the status of program and erase operations performed on the memory array of the non-volatile semiconductor memory. The status register includes a clock circuit that generates a clock signal in response to an output enable signal. The clock signal is coupled to a pair of latches that respond by coupling their signals to the pins. One latch couples an erase fail signal to a pin to indicate whether the memory array has been sucessfully erased. The other latch couples a program fail signal to a pin to indicate whether an addressed memory cell of the memory array has been sucessfully programmed.
