  • Patent number: 10102125
    Abstract: A peripheral component interconnect (PCI) device includes a first memory which includes a plurality of page buffers, a base address register which includes a plurality of base addresses, and a first address translation unit which translates each of the plurality of base addresses to a corresponding one of a plurality of virtual addresses. A map table includes a plurality of map table entries each accessed in correspondence to each of the plurality of virtual addresses, and maps each of the plurality of virtual addresses onto a physical address of physical addresses of the plurality of page buffers. The first address translation unit translates each of the plurality of virtual addresses to a corresponding one of the physical addresses using the map table.

  • Patent number: 8984219
    Abstract: A method is provided for writing data in a storage device, including a nonvolatile memory. The method includes receiving a pre-write command including a logical address and size information of write data, performing a pre-operation for optimization of a write operation based on the pre-write command, and writing the write data in the nonvolatile memory after the pre-operation is completed.

  • Publication number: 20130024608
    Abstract: A flash memory apparatus includes a flash memory and a control unit for controlling the flash memory. The flash memory includes multiple blocks, each block of the multiple blocks corresponding to multiple word lines, and each word line of the multiple word lines corresponding to a first bit page and at least one second bit page. The control unit is configured to map a logic address included in a host's write request received from a host to a first process page of multiple in a first process block of the multiple blocks, and to program the first process page. The first process page is only the first bit page.

  • Publication number: 20120297117
    Abstract: Disclosed is a data managing method of a storage device including a nonvolatile memory device. The data managing method includes detecting an update count of update-requested page data and allocating the update-requested page data to a first memory block or a second memory block based upon the update count, an erase count of the second memory block being different from that of the first memory block.
