ABSTRACT:
A single-chip memory-sense amplifier for a data processing system. There is disclosed a sense amplifier (level converter) and bus driver for use in a data processing system, to receive signal inputs from main memory and to drive a memory bus connecting output of the sense amplifier to the CPU. This sense amplifier is intended for use with memory fabricated from N-channel MOS technology. The circuitry of the sense amplifier is fabricated from bi-polar technology and formed on a single monolithic integrated circuit chip. The biasing scheme employed within the circuitry of the sense amplifier provides reliable operation, by making the amplifier relatively insensitive to power supply variations.
