Abstract
A computer system such as a mobile client system in which provision is made for management of flash memory. Flash memory management is done using variable block length and supports data compression. Blocks are allocated contiguously in each erase unit and each block starts with a header that contains the length of the block. Blocks are tracked using a single-level virtual address map which resides in random access memory (RAM). The mobile computer system may also include a housing, processor, random access memory, display and an input digitizer such as a touchscreen.
