Abstract: A computer including an interpreter that maps logical user write requests to physical block level write requests, a host storage driver having a disk driver interface for receiving block level write requests, a host storage disk connected to be controlled by disk control signals of the host storage driver, and a mirror system having a disk driver interface to the interpreter and a remote procedure call interface to a remote archive repository, the mirror system sending write requests and data to be written from the interpreter to the host storage driver and to the remote archive repository.

Abstract: A content addressable memory (CAM) system (50) is disclosed which includes a CAM array (52) for storing an array of data words. More than one data word is stored on each row with the bits of the data word columns interleaved with each other. The CAM array (52) is accessed during one of several modes of operation in accordance with signals from a bit line controller (54) which activate certain ones of a plurality of bit lines coupling the bit line controller (54) to the CAM array (52). The modes of operation, as indicated by a mode control signal, include a write mode, a read mode and a match mode. In first embodiment of the present invention, the bit line controller (54) sequentially accesses each of the columns of data words by selectively activating certain of the bit lines in accordance with a column address signal and the mode control signal.
