Abstract:
1. A method of operating an electronic memory module comprising: accepting a write command formatted for DRAM from a host device, the write command including a DRAM address; using a translation table to convert the DRAM address into a non-volatile EEPROM memory write address in an old page in a non-volatile EEPROM memory; reading previous data in the old page from the non-volatile EEPROM memory; updating the previous data with new data supplied in the write command to form an updated new page of data; writing a new page in the non-volatile EEPROM memory with the updated page of data and metadata that includes the DRAM address; and updating the translation table to map the DRAM address to the new page in the non-volatile EEPROM memory.
