Abstract
A storage system contains a solid state disk drive having a plurality of memory cells to store the files, including file system control information and data. In a high density mode, the solid state disk drive stores more than one bit per memory cell, and in a reliable mode, the solid state disk drive stores one bit per cell. A file configuration system stores file system control information in the reliable mode and stores data, when specified, in the high density mode. The file configuration system includes a multi-level cell extension unit that generates commands to the memory cells. A data compression unit is provided to compress file data. A block size for the data compression unit is calculated in accordance with the number of bits per cell stored in the high density mode. The file configuration system further includes an error detection and correction (EDC) unit to detect and correct data stored in the high density mode. The storage system may be implemented to operate with the personal computer memory card industry association (PCMCIA) standard.
