Bisr memory
WebBISR is used (bisr_h = 1), the faulty addresses can be replaced with redundant addresses to repair the SRAM. The inputs of SRAM in different operation modes are controlled by the … Webmemory are remapped with spare cells. By this redundancy organization the area of spare is efficiently utilized. 2.2 Architecture BISR circuit The BISR circuit mainly consists of MBIST and BIRA. Main memory contains multiplexers and repair registers. Multiplexers are used to switch between test/repair mode and normal

This paper presents a test scheduling approach for BISR memory cores under the constraint of maximum power consumption. An efficient test scheduling algorithm based on the early-abort probability is proposed.

It uses a built-in redundancy analysis (BIRA) circuit to allocate the redundancy when defects appear in the memory. The data are accessed from the redundancy allocation when the faulty memory is operative.
