ABSTRACT:
A circuit and method for varying the time of a write cycle. A variable timer circuit is provided coupled to a write simulation circuit. The write simulation circuit receives a signal from a start write sensing circuit indicating that data is being written to memory cells of the array. The write simulation circuit includes a memory cell replicate which replicates the time required for writing data to memory cells of the array. After the memory cell replicate has changed state, a signal is output via a switching circuit to the variable timer circuit for generation of a write termination signal. The memory cells are tested at various write cycle speeds by controlling the variable timer circuit. The variable timer circuit is set to terminate the write as quickly as possible after a successful write to the memory cells has been completed. The time interval for permitting a write can be selectively controlled over a large range to provide extremely fast devices or somewhat slower devices, all of which operate faster than standard devices on the market and thus are in high demand.
