Semiconductor integrated circuit device having an internally produced operation voltage matched to operation speed of circuit |
摘要 |
The semiconductor integrated circuit device incorporates a power supply circuit which forms an operation voltage that matches the operation speed of the internal circuit. Since the operation voltage is set in accordance with the operation speed required of the internal circuit, the internal circuit can be operated with a minimum required voltage even when there are process variations and temperature changes. In other words, a rational power supply is realized.
