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.

A semiconductor chip is provided with a function selection circuit for selecting memory functions according to the information stored in nonvolatile memory elements is sealed in a package, and the memory functions are set finally by writing the nonvolatile memory element in that state or in a state in which the semiconductor chip is mounted on a board. By setting the type of a semiconductor memory according to the above procedure, the process from the wafer process up to the assembling step can be made common, and hence the mass-productibity and the production control can be facilitated. Semiconductor memories having memory functions conforming to user specifications can be provided in a short time.
