Samsung patents cache system using dynamic index selection
Samsung has been granted a patent for a computer memory management technique that stores data based on its address and compression ratio. The system searches for requested data by checking two different sets of memory locations using different parts of the data's address.
In the filing’s own words
A system includes: cache memory; and a cache controller to: store a line of data in the cache memory according to an address of the line and a compression ratio of the line; and return a requested line of data based on a search in a first candidate set of the cache memory having a first index at a first index bit position of an address of the requested line, and in a second candidate set of the cache memory having a second index at a second index bit position of the address of the requested line. The first index bit position is different from the second index bit position.
What exactly they claim (claim 1)
1. A system comprising: cache memory; and a cache controller configured to: store a line of data in the cache memory according to an address of the line and a compression ratio of the line; and return a requested line of data based on a search in a first candidate set of the cache memory having a first index at a first index bit position of an address of the requested line, and in a second candidate set of the cache memory having a second index at a second index bit position of the address of the requested line, wherein the first index bit position is different from the second index bit position.
