Excerpt
Semiconductor storage. The area1 density of a 1-Mbit dynamic RAM is 1.2 million bits per sq mm. Of course, future generations will have still greater density. Putting eight or nine of these 4-Mbit DRAMS on a card provides storage capacity equivalent to a 4 Mbyte hard disk, but with the direct access advantage of semiconductor architecture. These semiconductor “disks” should become more competitive with hard disks during the 1990s as DRAM density increases and prices decline.

Claims
Memory manager with file allocation table

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.
