Abstract
A clamped-bit-line sense amplifier (CBLSA) capable of very high-speed operation in one-transistor (1T) DRAM applications has been developed. Results from an experimental test chip demonstrate that the speed of the new circuit is insensitive to bit-line capacitance. Circuit speed is also found to be insensitive to the initial bit-line difference voltage. The CBLSA maintains a low impedance fixed potential on the bit lines during sensing, virtually eliminating sensitivity to inter-bit-line noise coupling and minimizing power supply bounce during sensing. The new sense amplifier operates at higher speeds than conventional circuits and still dissipates less power.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
