Abstract: A method of performing a write operation, the method comprising: comparing a data pattern of a currently received command directing a write operation to data patterns of at least one previously received command; and performing a write operation, based on the currently received command directing the write operation, by writing the data patterns of the at least one previously received command instead of the data pattern of the currently received command when the data pattern of the currently received command directing the write operation is identical to the data patterns of the at least one previously received command

Abstract: A flash memory system includes; a controller that determines at least one parameter related to data reliability based on temperature information and generates a control signal based on the at least one parameter; and a memory device that comprises one or more memory cell arrays and provides the controller with read data corresponding to a read command received from the controller.

Abstract: A method of managing a storage area of a memory device in a memory system is provided. A first data is received. The first data has a logical address to be written to the memory device having a plurality of memory blocks. The first data is classified into one of a hot data and a cold data based on an update frequency of the first data. A memory block is defined into a first storage area and a second storage area based on an amount of charge loss of a memory cell in the memory block. A memory cell of the first storage area has charge loss greater than a memory cell of the second storage area. The logical address of the first data is converted to a physical address of the memory device according to a result of the classifying of the first data. The first data is written to a memory cell having the physical address of the memory device.

Abstract: An apparatus and method of reading and writing data from and on a storage medium include receiving at least one of file information and file data from a host, generating a logical block address corresponding to the one of the file information and the file data, and writing the one of the file information and the file data at the generated logical block address

Abstract: Method for driving a plasma display panel, wherein an address reinforcement period is added between an address period and a sustain period, and a scan voltage Vw of positive polarity and a third DC voltage Zdc3 are applied, for inducing floating charges in discharge cells, whereby preventing erratic discharge caused by the floating charges at a high temperature.

Abstract: A method optimizing a recording current in consideration of operating temperatures of a hard disk drive and a method of setting a recording density in consideration of tracks per inch (TPI) or adjacent track erasure (ATE) characteristics. The method of optimizing the recording current measures a rate of errors under a test condition corresponding to the operating temperature of a hard disk drive, while changing a recording parameter, selects a recording parameter value corresponding to a smallest rate of errors, and optimizes the recording current for the hard disk drive under operating environmental conditions using the selected recording parameter value.
