ABSTRACT:
A memory cell is comprised of a cross-coupled master latch and a cross-coupled slave latch. The memory cell includes means for switching on and off power supplies connected to the master latch and the slave latch so as to control the direction of shift in a bidirectional shift. Data is shifted in a first direction when the power supply connected to the master latch is switched off, and data is shifted in a second direction when the power supply connected to the slave latch is switched off.
