Abstract:
PURPOSE: A nonvolatile memory system and operation method thereof are provided to effectively manage uncorrectable sector information by storing the uncorrectable sector information with a page stored in the sector data. CONSTITUTION: A nonvolatile memory(40) includes data area and uncorrectable information area. The data area includes a sector area storing sector data. The uncorrectable information area stores uncorrectable sector information about the sector area. A controller(24) includes information generating unit which generates the uncorrectable sector information according to the command of a host. The uncorrectable sector information indicates whether the sector area is appointed to the uncorrectable sector area.
Abstract:
PURPOSE: A method and apparatus for interfacing between a semiconductor storage device and a host are provided to control the performance of the semiconductor storage device by setting a performance control parameter to a specific value. CONSTITUTION: A set request command is received from a host(S610). A semiconductor storage device sets the requested performance control parameter to a specific value in response to the set request command. The semiconductor storage device transmits a set response signal(S620).
Abstract:
PURPOSE: A semiconductor device and an address mapping method thereof are provided to efficiently allocate storage space between dissimilar log types by changing a log block to one log block according to a log type. CONSTITUTION: A log type decision part(110) selects one among a first log type and a second log type which are dissimilar type according to the request of a processor of a semiconductor device. A first type log part(120) receives and writes a logical address for programming to a flash memory and program data to corresponding block when a control signal is selected to a first log type. A second type log part(130) receives and writes a logical address for programming to a flash memory and program data when a control signal is selected to a second log type. A merge part(140) changes a log block which is included in a log part among a first type log part and a second type log part to the log block of a different log part in response to the conversion request included in a control signal.
Abstract:
PURPOSE: A non-volatile memory apparatus, an operation method thereof, and apparatuses including the same are provided to effectively manage data stored in a flash memory by preferentially performing a garbage collection process with respect to data blocks which requires a refresh process. CONSTITUTION: A flash memory(60) comprises a plurality of data blocks. A memory controller(50) comprises a garbage collection block determination part(52), a refresh block determination part, and a garbage collection execution part. The garbage collection block determination part determines first data blocks among the plurality of data blocks. The refresh block determination part determines second data blocks among the first data blocks. The garbage collection execution part preferentially performs a garbage collection process with respect to the second data blocks.
Abstract:
PURPOSE: A semiconductor storing apparatus and a method for adjusting the performance of the semiconductor storing apparatus are provided to effectively adjust the performance of the apparatus by inserting idle time after the operating process of the apparatus according to the workloads of the apparatus. CONSTITUTION: A controller receives a writing command from a host(S210). Writing data is received from the host(S230). The received writing data is programmed in the memory cell array of a non-volatile memory(S250). When the writing data is programmed, a semiconductor storing apparatus transmits the writing operation complete signal to the host(S270). Idle time is inserted after at least one of processes according to set performance levels.
