1. A computer system comprising:
- a content-addressable physical memory including two or more physical memory blocks, each of said physical memory blocks having a fixed storage capacity, wherein some of said memory blocks are indicated as being in an active state and some of said memory blocks are indicated as being in an inactive state; and
a memory controller providing a non-duplicating write capability, wherein data to be written to said physical memory is compared to contents of a set of said memory blocks that are indicated as being in an active state at the time of writing to avoid storage of identical data after completion of the non-duplicating write.

Abstract
Improved memory management is provided according to a Hierarchical Immutable Content Addressable Memory Processor (HICAMP) architecture. In HICAMP, physical memory is organized as two or more physical memory blocks, each physical memory block having a fixed storage capacity. An indication of which of the physical memory blocks is active at any point in time is provided. A memory controller provides a non-duplicating write capability, where data to be written to the physical memory is compared to contents of all active physical memory blocks at the time of writing, to ensure that no two active memory blocks have the same data after completion of the non-duplicating write.

7. A method of computer system memory management comprising:
-
in a content-addressable physical memory having two or more physical memory blocks, each of said physical memory blocks having a fixed storage capacity, indicating that some of said memory blocks are in an active state and some of said memory blocks are in an inactive state; and using a memory controller to compare data to be written to said physical memory to contents of a set of said memory blocks that are indicated as being in an active state at the time of writing to avoid storage of identical data after completion of the non-duplicating write. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
