Built-in Self-Test Repair (BISTR) Technique For Radom Access Memories (RAMs)
Built-in self-test repair (BISTR) technique has been most widely used to test repair embedded random access
memories (RAMs). This paper proposes a reconfigurable BISTR (ReBISTR) scheme totest repairing RAMs with different
sizes and redundancy organizations. An efficient redundancy BIST algorithm is proposed to allocate redundancies of
defective RAMs. In the ReBISTR, a reconfigurable built-in self-test and test repairredundancy analysis is (ReBIRA) design
circuit is to perform the redundancy algorithm for various RAMs. Also, an adaptive reconfigurable methodology is proposed
to reduce the test repair setup time when the RAMs are operated in normal mode. Due to the complexity of memory
architectures, the possibility of occurring manufacturing defects is high. Hence memory testing is necessary. Built inSelf-
Testrepair (BISTR) has been proven to be most cost-effective and widely used solutions for memory testing. BISTR
technique is used to reduce test repair time. The design architecture is simulatedin Xilinx ISE 14.7 tools.
