The manager for a computer memory of Claim 1 further comprising: an initialization routine, each block having header information, the initialization routine for gathering information from the headers and from the allocation tables and storing the gathered information in a memory cache.

A method of addressing a data region in a computer memory device, the memory divided into blocks, each block having a physical block number, the method comprising the steps of: storing an allocation table in each block, the allocation table having entries that indicate an offset of a data region within the block and that have an entry index; storing a logical block number in each block; identifying a data region by logical block number and allocation table entry index; and generating an address to the identified data region based on the logical block number and the allocation table entry index.

A method of leveling block erasures in a block-erasable, programmable, read-only memory, the method comprising the steps of: identifying a first block that has been erased; identifying a second block that has been erased a fewer number of times than the first block; and swapping the data in the first block with the data in the second block.

The method of Claim 10, each block having header information, further comprising the steps of: gathering information from the headers and from the allocation tables; and storing the gathered information in a memory cache.

The manager for a computer memory of Claim 1 further comprising: a data area deallocation routine for setting an allocation table entry that is in the allocated state to a deallocated state; and a block reclamation routine for reclaiming data areas corresponding to allocation table entries that are in that deallocated state.

The method of Claim 4 wherein the allocated data regions are copied into contiguous memory locations in the spare block.

The method of Claim 6 or 7 wherein the computer memory device is a block-erasable, programmable, read-only memory.

The method of Claim 10, further comprising the steps of: setting an allocation table entry that is in the allocated state to a deallocated state; and reclaiming data areas corresponding to allocation table entries that are in that deallocated state.

A manager for a computer memory comprising: a block allocation routine, the memory divided into blocks of memory locations, each block having an allocation table and a data region divided into data areas, each allocation table having entries corresponding to region data areas, the block allocation routine for selecting a block in which to store data; a data area allocation routine for selecting a data area within the data region for the selected block in which to store data, for selecting an allocation table entry to correspond to the selected data area, and for setting the selected allocation table entry to correspond to the selected data area and to an allocated state; and a storage routine for storing data in the selected data area.

A method of reclaiming deallocated space in a block-eraseable, programmable, read-only memory, the memory having blocks, the method comprising the steps of: identifying data regions as deallocated or allocated in a block to be reclaimed; erasing a spare block; and copying allocated data regions from the block to be reclaimed to the spare block whereby a memory area corresponding to the deallocated data region is reclaimed for allocation.

The method of Claim 6 wherein the step of generating an address includes the steps of: determining the physical block number from the logical block number, each block having a corresponding start address; retrieving the offset from the allocation table entry in the determined physical block number that is indexed by the allocation table entry index; and adding the retrieved offset to the start address of the block with the determined physical block number to generate the address of the identified data region.

A method of managing memory in a block-erasable, programmable, read-only memory, the memory being divided into blocks of memory locations, each block having an allocation table and a data region divided into data areas, each allocation table having entries corresponding to region data areas, the method comprising the steps of: selecting a block in which to store data; selecting a data area within the data region for the selected block in which to store data; selecting an allocation table entry to correspond to the selected data area; setting the selected allocation table entry to correspond to the selected data area and to an allocated state; and storing data in the selected data area.

A method of managing memory in a block-erasable, programmable, read-only memory, the memory being divided into blocks of memory locations, each block have a table and a data region divided into data areas, each table having entries corresponding to the data areas, the method comprising the steps of: selecting a block in which to store data; selecting a data area within the data region for the selected block in which to store data; selecting a table entry to correspond to the selected data area; setting the selected table entry to correspond to the selected data area and to indicate that the data area contains data; and storing data in the selected data area.
