A STORAGE DEVICE SUPPORTING LOGICAL OPERATIONS, METHODS AND STORAGE MEDIUM

摘要

A storage device has a plurality of storage cells for storing data values. Control circuitry is provided to simultaneously couple at least two cells to at least one common signal line. Sensing circuitry is provided to sense a signal on the at least one common signal line, which indicates a result of a logical operation applied to the data values stored in each of the at least two storage cells. This allows logic operations such as AND, OR, XOR, etc. to be performed within a storage device so that it is not necessary to read out each data value independently and transfer each data value to a separate processing circuit in order to find the result of the logical operation. This helps to improve performance within a data processing apparatus having the storage device.

1. A storage device comprising:
a plurality of storage cells to store data values; control circuitry to simultaneously couple at least two storage cells of the plurality of storage cells to at least one common signal line, wherein the at least two storage cells comprise storage cells within a same column, and the at least one common signal line comprises a pair of bitlines corresponding to the same column; and sensing circuitry to sense a signal level on at least one of said at least one common signal line which is indicative of a result of a logical operation applied to the data values stored in each of said at least two storage cells.
