The operating method of the storage device includes receiving write data to be written at the plurality of memory cells; determining whether the received write data is LSB data to be written at the plurality of memory cells; and encoding the write data according to the determination. The write data is encoded according to the write data when the write data is LSB data to be written at the plurality of memory cells. The write data is encoded according to the write data and encoding data of lower data of the write data to be written at the plurality of memory cells when the write data is not LSB data to be written at the plurality of memory cells.

A memory system includes: a bit counter and a regression analyzer. The bit counter is configured to generate a plurality of count values based on data read from selected memory cells using a plurality of different read voltages, each of the plurality of count values being indicative of a number of memory cells of a memory device having threshold voltages between pairs of the plurality of different read voltages. The regression analyzer is configured to determine read voltage for the selected memory cells based on the plurality of count values using regression analysis.

A partial data changing method of a memory controller includes receiving a request to change partial data from a host; detecting an error of old data, the old data being partial data read from a memory device using an error detection code; if the old data is not erroneous, calculating a data difference between new data provided from the host and the old data, and calculating a new parity using the data difference and an old parity read from the memory device; and storing the new data and the new parity at the memory device.
摘要:
A write method of a data storage device including a storage media includes receiving data to be stored in the storage media; judging whether the received data is compressed data, without externally provided additional information; and selectively compressing the received data according to the judgment result, wherein the judging whether the received data is compressed data is made based on a distribution of actual symbols included in at least part of the received data.
