ABSTRACT:
A method of optimized access of information in the memory subsystem of a computer system that requires the writing of information in blocks of continuous memory space is disclosed. The inventive method of information storage for storing a file in a memory device requiring block writing comprising the steps of first comparing the size of the file with each free block of the memory device for selecting a best-fit block therefrom. A fitted segment of the file corresponding to the best-fit block is then stored into the best-fit block. The comparing step and the storing step are then repeated if a remainder of the file remains after the storing until the entirety of the file has been stored in the memory device. An information storage system is also disclosed to comprise a memory device requiring block writing and a file system. The file system is built on top of the software driver module of the memory device and provides a memory block assignment algorithm for implementing an efficient information storage usage for storing a file in the memory device.
