Abstract
A semiconductor integrated circuit device which guarantees the characteristics of writing to and reading from the built-in memory even when the manufacturing process conditions are varied, 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. The semiconductor integrated circuit device is provided with a cache memory which includes a BIST circuit composed of a pattern generator, a pattern comparator, an output register, a register controlled by a register control 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.
