Storage arrangement for e.g. silicon chip memory cards has data compression-decompression module that is provided between host-controller interface and flash-controller interface and that is connected to microprocessor

摘要

The storage arrangement includes a controller (10) with a host-controller interface (104). A data compression-decompression module (108) is provided between the host-controller interface and a flash-controller interface (106). The data compression-decompression module is connected to a microprocessor (102) and includes a data compression circuit and several algorithmic instruction and parameter tables. The microprocessor decides about the best compression combination from the incoming data type.
