Abstract
A static RAM, including a bit-line-charging transistor connected, in parallel to the load transistor, between each bit line and the power supply. These bit-line-charging transistors are controlled by a control signal generator circuit, which provides a timed pulse to their gates at the conclusion of each write cycle. The width of this timed pulse is selected such that bit lines which have been driven to a low level (e.g., zero volts) during a write cycle are rapidly recharged to the low level (e.g., 2.5 volts) to which they might have been driven during a read cycle. Thus, reverse readout operations (e.g., where a '1' is read immediately after a '0' has been written) no longer pose an obstacle to improving read operation speed, and speed and density can be improved.
