Abstract
The present invention is directed to a magnetic memory device that emulates DRAM and provides a plug-in or drop-in replacement for DRAM. The memory device includes one or more magnetic memory banks for storing data; a controller configured to issue a dormant write command upon receiving a refresh command for recharging DRAM capacitors; and a memory cache for storing temporary data and configured to save the temporary data to the one or more magnetic memory banks upon receiving the dormant write command from the controller. The memory device may be compliant with at least one version of low power DDR (LPDDR) Specification or at least one version of DDR SDRAM Specification.
