Sequential access memory elements
Abstract:
Integrated circuits with sequential access memory cells are provided. A sequential access memory cell may include an inverter-like circuit, an inverter, a preset transistor, an access transistor, and a read circuit. The inverter-like circuit and the inverter are cross-coupled to form a bi-stable latch that is powered by a positive power supply line and that has first and second storage nodes. The preset transistor may be connected between the positive power supply line and the first storage node. The inverter-like circuit may include a transistor in its pull-down path. The preset transistor is enabled while the transistor is disabled to write a “1” at the first storage node. The access transistor may be used to write a “0” into the cell. The read circuit may be connected to the second storage node to read data from the cell without inducing a voltage rise at the second storage node.
