1. A method of operating a memory device comprising: applying power to the memory device to initiate a power-up operation; performing a one-time read operation of configuration bits stored in non-volatile circuitry of the memory device during the power-up operation, and applying a conversion algorithm to the configuration bits to convert the configuration bits to operational timing data representing memory device access operation wait cycles; storing the operational timing data in a random access memory location of the memory device; receiving an externally provided command to execute an access operation on the memory device; in response to the received command, reading the operational timing data from the random access memory location; and performing the access operation on the memory device by applying the operational timing data read from the random access memory.
