Title: Semiconductor storage device
Inventor: SHIMIZU SHIN
IPC: G11C29/00
Filed: 1993-04-09
Abstract: PURPOSE:To make a defective memory cell array recoverable on the spot at the time of testing. CONSTITUTION:Antifuses 17, 24 and switching means 16, 23 are provided between a power supply terminal to which an operating voltage is ordinarily supplied and the ground, and by conducting each switching means, a voltage is applied to both ends of each fuse. Then, a signal from an address selecting means 5 is inputted in the control terminal of each switching means. Also, a high voltage is supplied to a power supply terminal at the time of rescuing process. When a defect exists in a normal memory cell array 1, the switching means of which an address is assigned is turned on, a high voltage is applied to both ends of the antifuse, and the antifuse is conducted. Thus, regardless of an address assignment, the normal memory cell array is inactivated, and instead, a redundant memory cell array 2 is activated. Consequently, with the antifuse being conductive through a defective address information, no special device is necessitated and the operation efficiency is enhanced.
