摘要:
A solid state drive (SSD) including a storage that includes a plurality of flash memories configured to be independently drivable and a controller to receive an input/output (I/O) request from a host, to split the I/O request into a plurality of sub-requests each having a size configured to be capable of being processed independently by each flash memory, and to process the I/O request based on the sub-requests.
摘要:
A memory system includes a variable resistance memory configured to input and output data by a first unit and a translation layer for managing the degree of wear of the variable resistance memory by a second unit, different from the first unit.
摘要:
A non-volatile mass storage memory and an input/output processing method using the memory are provided. The memory device includes a storage unit including a non-volatile random access memory and a flash memory and a controller to control the storage to process an input/output request. Accordingly, system memories having different purposes and functionalities, such as a flash memory and a dynamic random access memory (DRAM), may be integrated with each other.

摘要:
A method and apparatus for writing data to and reading data from a phase-change random access memory (PRAM) include encoding original data using a predetermined encoding function, selecting data, from among the original data and the encoded data, which require less power when being written to the PRAM, writing the selected data to the PRAM, generating marking information related to the selected data, and writing the marking information to the PRAM. Therefore, power consumption can be reduced when data are written to the PRAM.

摘要:
The present invention relates to a mapping information managing apparatus and method for a non-volatile memory supporting different cell types, and more particularly, to a mapping information managing apparatus and method for a non-volatile memory supporting different cell types capable of managing mapping information considering physical characteristics of each cell type in the non-volatile memory supporting different cell types in which bits represented by one cell are different from each other. A mapping information managing apparatus for a non-volatile memory supporting different cell types includes: a user request unit used for a user to request a predetermined operation by using a logical address; a non-volatile memory comprising a plurality of memory areas having different cell types; and a mapping information managing unit storing mapping information on user data written to a second memory area of the plurality of memory areas in a first memory area.
摘要:
Provided are a nonvolatile memory and an apparatus and method for deciding data validity for the same, in which validity of data stored in the nonvolatile memory can be decided. The nonvolatile memory includes a memory cell storing data bits in a plurality of pages included in a predetermined block through a plurality of states realized by at least two bits. The block includes a first page in which data bits for determining validity of data bits written by a user are stored, and a second page in which the data bits written by the user are stored.
