Abstract

A method of minimizing memory access time on a memory with multiplexed address inputs between data stored in locations in memory in the same row but in different columns. First data is accessed at a predetermined column and row location. The predetermined row location of the first data is then recorded. The location of second data is then recorded. Then the locations of the first and second data are compared. A row compare signal is generated if the row value of both first and second data are identical. Only the column address is varied in response to the row compare signal.
