MEMORY DEVICE AND METHOD HAVING ON-BOARD PROCESSING LOGIC FOR FACILITATING INTERFACE WITH MULTIPLE PROCESSORS, AND COMPUTER SYSTEM USING SAME

摘要

A memory device includes an on-board processing system that facilitates the ability of the memory device to interface with a plurality of processors operating in a parallel processing manner. The processing system includes circuitry that performs processing functions on data stored in the memory device in an indivisible manner. More particularly, the system reads data from a bank of memory cells or cache memory, performs a logic function on the data to produce results data, and writes the results data back to the bank or the cache memory. The logic function may be a Boolean logic function or some other logic function.

主权项

1. An integrated circuit memory device comprising:
a plurality of memory cells; a logic unit configured to perform a logic function on data received from the plurality of memory cells and output a result responsive to the logic function; a select circuit coupled to a plurality of terminals and the logic unit, and configured to select between the plurality of terminals and the logic unit; and a write driver coupled to the select circuit and configured to write an output of the select circuit to the plurality of memory cells.
