Abstract
The present invention provides a memory array having an array structure that has at least one memory cell, including a word write bit line and a single transfer line. The memory array is also provided with a two-stage memory cell having a speculative storage node, a non-speculative storage node, and a circuit. The two-stage memory cell is electrically coupled to the array structure. Activation of the circuit causes a speculative data value stored in the speculative storage node to be written to the non-speculative storage node.
