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.
Claims18
A non-volatile semiconductor memory comprising a first memory device and control circuitry operable to:
- issue an access command to the first memory device;
- request a command status from the first memory device after a status delay;
- when the command status indicates the first memory device has completed the command, measure a first access time of the memory device;
- and
- modify an access sequence of the first memory device in response to the access time.
A method of operating a non-volatile semiconductor memory comprising a first memory device, the method comprising:
- issuing an access command to the first memory device;
- requesting a command status from the first memory device after a status delay;
- when the command status indicates the first memory device has completed the command, measuring a first access time of the memory device;
- and
- modifying an access sequence of the first memory device in response to the access time.
