Abstract
A non-volatile semiconductor memory is disclosed comprising a first memory device and control circuitry operable to issue an access command to the first memory device. A command status is requested from the first memory device after a status delay. When the command status indicates the first memory device has completed the command, a first access time of the memory device is measured. An access sequence of the first memory device is then modified in response to the access time.
