ABSTRACT:
A random access memory array includes random access memory elements arranged in a rows and columns. The elements of each row have a word line and a write digit line and the elements of each column have a bit line and a write bit line. A first selection circuit/transistor for each row has a first source-drain path coupled in the write digit line and a gate terminal coupled to the word line. A second selection circuit/transistor for each column has a second source-drain path coupling in the write bit line and a gate terminal coupled to the bit line. A first write signal is applied to one word line to actuate the first selection circuit/transistor for the row corresponding to that one word line and cause a write current to flow through the first source-drain path of the actuated first selection circuit/transistor and the corresponding write digit line to write data into certain memory elements in that row. A second write signal is applied to one bit line to actuate the second selection circuit/transistor for the column corresponding to that one bit line and cause a write current to flow through the second source-drain path of the actuated second selection circuit/transistor and the corresponding write bit line to write data into at least one memory element in that column.
