A method of operating a non-volatile memory device is provided. The device includes a latch, a page buffer and blocks, each of which includes pages. The method includes: receiving a page command for a write operation corresponding to a page of one of the blocks; receiving a write command for writing data to the page buffer; latching preexisting latched data or random data generated as latched data; writing the latched data to a page of a new block from among the plurality of blocks that corresponds to a page address based on the write command; and repeatedly updating the page address and repeatedly writing the latched data to additional pages corresponding to each updated page address until each page of the new block has been written to.

Method and apparatus for configuring a non-volatile memory device without data transfer

A method of accessing data from a data storage device includes transmitting a request including a first part to the data storage device, based on availability of memory in host device. The first part includes data access information and one or more parameters for accessing data from data storage device. The method further includes receiving a first notification from the data storage device, indicating a transfer of the data to a storage buffer associated with the data storage device. The method further includes accessing the data from the data storage device by transmitting second part of request to the data storage device. The second part includes buffer information associated with a host buffer of host device. The data is transferred by the data storage device from the storage buffer to the host buffer of host device using buffer information.

Method and a host device for accessing data from a data storage device

In a method of organizing data during refresh cycles of a memory device, a read request is sent to a non-volatile flash memory including a plurality of source blocks and a plurality of destination blocks. Data of the plurality of source blocks are read upon sending the read request. The frequency of bit error rate (BER) for the data stored in the plurality of source blocks is identified. The data within the plurality of source blocks are grouped and segregated based on the frequency of BER and a threshold value. The plurality of source blocks and the plurality of destination blocks are refreshed by moving the data present in the plurality of source blocks to respective destination blocks based on the segregated data and moving data from the respective destination blocks to other respective destination blocks.
