Slew-rate control system for synchronous dynamic random access memory, changes output data or transition speed based on signal which shows variation in electrical potential difference |
摘要 |
Electrical potential difference of two power supply sources are sampled at a predetermined time and a signal is generated which describes electrical-potential difference variation. The change of transition speed or output data of output buffer circuit (4) is performed according to generated signal.
