Each of the single port SRAM memory cells includes a first write switch, a second write switch and a latch.

The second write switch is electrically connected to a second word line and is turned on by a second turn-on signal transmitted by the second word line. When the memory is in the write mode, the second write switch is turned on by the second turn-on signal having a delay with respect to the first turn-on signal, thereby blocking the pseudo read of the unselected memory cell.

Abstract: An in situ pulse-based delay variation monitor that predicts timing errors caused by process and environmental variations is revealed. The monitor includes a sequential storage device having a mater storage device and a slave storage device, a transition detector that is electrically connected to a node set on an electrical connection pathway from a master storage device to the slave storage device, and a warning signal generator electrically connected to the transition detector. The transition detector receives output of the master storage device to form a warning area by delay buffer, and generates a pulse width output correspondingly according to transition of the data input. Thus the warning signal generator generates a warning signal according to logic action at the pulse width and the clock input when the data input reaches the warning area. Thereby timing errors caused by static process variations and dynamic environmental variations are predicted.
