Memory system using schottky diodes to reduce load capacitance

摘要

A computer memory system is disclosed with an input/output circuitry capable of separating the load separating the load capacitance of an output circuit of a semiconductor memory connected to a memory bus from the memory bus. In order to separate the load capacitance of a semiconductor memory connected to a memory bus signal line, a Schottky diode is arranged between the semiconductor memory and the memory bus line, and a voltage control circuit is provided to control whether a reverse bias voltage is applied to the Schottky diode. The speed of signal transmission does not decrease even when a large number of semiconductor memories are connected to the memory bus since the load capacitance of the semiconductor memories is separated from the bus. Therefore, it is possible to construct a high speed and large capacity memory system.
