The present disclosure is drawn to, among other things, a method of managing a memory device. In some aspects, the method includes determining whether a first address for a page in a first memory region is mapped in a map table, setting a target address as a second address identified in the map table as being mapped to the first address, setting the target address as the first address, determining a number of bits that fail in each word of a plurality of first-layer error correction code (ECC) words for the target address, and adding the target address to the map table, writing-back contents from the target address to a repair address in the first memory region, and updating the map table by mapping the target address to the repair address.

Systems and methods for monitoring and managing memory devices

The present disclosure is drawn to, among other things, a method of managing a magnetoresistive memory (MRAM) device. In some aspects, the method includes receiving a configuration bit from a write mode configuration register. In response to determining the configuration bit is a first value, the MRAM device is operated in a NOR emulation mode. In response to determining the configuration bit is a second value, the MRAM device is operated in a persistent memory mode.

Systems and methods for NOR page write emulation mode in serial STT-MRAM

A special mode key match comparison module has N-storage elements and a special mode key match comparator. The N-storage elements accumulate a serial data stream, and then determine whether a digital device should operate in a normal user mode, in a public programming mode, or in a particular private test mode. To reduce the possibility of accidentally decoding a false test or programming mode, the data stream has a sufficiently large number of N-bits to substantially reduce the probability of a false decode. To further reduce the possibility of accidentally decoding a programming or test mode, the special mode key match comparison module may be reset if less or more than N-clocks are detected during the accumulation of the N-bit serial data stream. The special mode key match data patterns may represent a normal user mode, a public programming mode, and particular private manufacturer test modes.
