Semiconductor integrated circuit device, method of manufacturing the device, and computer readable medium

Abstract

A semiconductor integrated circuit device supplied as an IP (Intellectual Property), etc., a method of manufacturing the device, and a medium for storing a processing procedure for deciding the number of delay circuits built in the device used for designing, more particularly to a semiconductor integrated circuit device which guarantees the characteristics of writing into and reading from the built-in memory even when the manufacturing process conditions are varied. The semiconductor integrated circuit device is provided with a cache memory which includes a BIST circuit composed of a pattern generator, a pattern comparator, and an output register; a register controlled by a register control signal and a register write signal; a variable delay circuit controlled by the register; word lines, and a sense amplifier enable signal line. The timing for enabling the sense amplifier is changed and the memory is measured by a BIST circuit at the timing, thereby deciding the optimal timing.
