摘要： A single-port RAM generator architecture, for the generation of different RAM structures in a CAD environment, and to test the operation capabilities of the different RAM structure. The architecture includes a Static RAM matrix and a self timed architecture, which includes a control logic, both a dummy row and a dummy column having respectively equivalent load of a word line and of bit column of said matrix. The dummy column is discharged at a faster rate than the corresponding bit column optimizing the timing and reducing power consumption. Different column multiplexer selections provide different RAMs for a selected RAM size, each having slightly different silicon area and timing performance.
