Patent ID: 8255661

Claim:
A data storage system comprising: a non-volatile memory; a first interface operable to receive a write command from a host, the write command comprising a host write data block having a host logical block size; and a block mapping bridge operable to: divide the host write data block into a plurality of transfer data blocks, wherein each transfer data block having a device logical block size smaller than the host logical block size; transmit the transfer data blocks through a second interface to control circuitry, wherein the control circuitry operable to: accumulate the transfer data blocks into a physical data block having a device physical block size equal to a first integer multiple of the device logical block size, wherein: the host logical block size is a second integer multiple of the device physical block size; the first integer is greater than one; and the second integer is at least one; and write the physical data block to the non-volatile memory.
