Abstract:
A non-volatile memory apparatus comprising:a receiving device that receives one of a request to write data at a logic sector address and a request to read data from a logic sector address that is transmitted from a host computer;a volatile memory device that stores a first address conversion table;a non-volatile memory device that stores a second address conversion table and data;first program code that obtains a physical location of the second address conversion table stored in the non-volatile memory device based on the logic sector address relative to the request received by the receiving device and the first address conversion table stored in the volatile memory device;second program code that obtains the second address conversion table stored in the non-volatile memory device based on the physical location obtained by the first program code, and obtains a physical location in the non-volatile memory apparatus at which data is written or read based on the logic sector address relative to the request received by the receiving device and the second address conversion table; anda data access device that writes the data relative to the request which is received by the receiving device, or reads the data relative to the request which is received by the receiving device, with respect to the physical location of the non-volatile memory device obtained by the second address obtaining device.
