  • Patent number: 5355464
    Abstract: Circuitry for suspending an automated sequence for a nonvolatile semiconductor memory is described. The circuitry and memory reside on the same substrate. The circuitry includes a circuit for suspending erasure at a predetermined state of the erase sequence when a suspend signal is active and a circuit for resuming erasure at a predetermined state of the erase sequence when the suspend signal goes inactive. A method for suspending automated erasure sequence of a non-volatile semiconductor memory is also described. A suspend signal is received and erasure is suspended after a first erasure step of the erase sequence if suspend signal is active. Erasure resumes at a second erasure step of the erase sequence when the suspend signal goes inactive.
