Method and apparatus for in-system repair of memory in burst refresh
In a repair of a random access memory (RAM), an error information is received, a fail address of the RAM identified, and a one-time programming applied to a portion of the redundancy circuit while a content of the RAM is valid. Optionally, the RAM is a dynamic access RAM (DRAM), a refresh burst is applied to the DRAM, followed by a non-refresh interval, and the one-time programming is performed during the non-refresh interval.
