ABSTRACT:
A start write sensing circuit for sensing a start of a write is coupled to a write simulation circuit. The write simulation circuit preferably includes a memory cell replicate to mimic the amount of time required for writing data to the memory cell. The state of the data stored in the memory cell replicate is changed upon the write sensing circuit sensing the start of a write. The memory cell replicate is preferably constructed using the same structure, design, and process as the memory cells of the array so as to accurately simulate the time required for writing data to a memory cell in the array. Upon the write to the memory cell replicate being completed, a write termination signal is generated for terminating the write signal. The write termination signal also is a reset signal for resetting circuits of the array to prepare for the next cycle, whether it be a read or a write.
