Pre-charged exclusionary wired-connected programmed redundant select |
摘要 |
Therefore, according to the present invention, replacement of defective elements of an integrated circuit memory device by a redundant array is accomplished using a redundant decode scheme which is as fast as or faster than the standard decode. An exclusionary wired-connection redundant select circuit, which is programmable and pre-charged, allows the redundant array to be programmed such that any defective element may be replaced in a quick manner. The exclusionary wired-connection redundant select circuit is enabled by programming a programmable element of an enable circuit contained within the exclusionary wired-connection redundant select circuit and is programmed by disconnecting all programmable elements of the select circuit not representative of the defective element to be replaced. The output signal of the exclusionary wired-connection redundant select circuit propagates to decode output slave latch circuitry where it is latched and stored.
