Apparatus and methods for processing data through a random access memory system

摘要

Apparatus and methods are disclosed for providing an increased flexibility and rate in processing data in a random access memory (RAM) system. The apparatus comprises, in a first embodiment, a switching circuit which is coupled to the word lines of the RAM array and which is selectively operable in two modes. The switching circuit operates in a first mode to transmit word line signals to a single row of memory cells in the RAM array in accordance with principles well known in the prior art. The switching circuit is responsive to a control circuit, and operates in a second mode to alter, along the row of memory cells in the RAM array, the word line signal path, to provide simultaneous accessing of portions of at least two adjacent rows of memory cells in the RAM array. Such simultaneous accessing allows the processing of more data through the memory system that was previously possible in accordance with principles known in the prior art.
