    Abstract: A random access memory array includes first random access memory elements arranged in a plurality of rows and columns for storing data words at a multiple memory locations. The memory array further includes second random access memory elements arranged in at least one additional column. Each second random access memory element is associated with a memory location to store a flag value indicative of whether the data word stored at that memory location is a true or complement version. The individual memory elements may comprise magnetic random access memory elements. Alternatively, the individual memory elements may comprise flash memory cells.

    Abstract: An integrated circuit includes an array of memory cells that are selected by rows and read by columns. The columns are first precharged by an internal signal to then read the memory cells. The read is responsive to an edge of a clock signal and the read is of an unknown delay. A multiplexer output provides the internal signal. The multiplexer includes a plurality of inputs electrically connected to delay lines of different delay sizes that receive the edge of the clock signal. A multiplexer control circuit selects a delay line to provide the internal signal as soon as possible after the unknown delay.

    Abstract: A magnetic random access memory element is made from a first magnetic tunnel junction and a second magnetic tunnel junction. These magnetic tunnel junctions are connected to each other in a series resistive circuit. The connected first and second magnetic tunnel junctions are connected to a bit line through an access transistor. A write bit line and a write data line are associated with each of the first and second magnetic tunnel junctions. By application of appropriate currents to these lines, the magnetic vector orientation with each of the first and second magnetic tunnel junctions can be controlled so as to store information within the element in any one of at least three logic states.

    Abstract: A magnetic random access memory element is made from a first magnetic tunnel junction and a second magnetic tunnel junction. A latching circuit includes a false node that is connected to the first magnetic tunnel junction and a true node that is connected to the second magnetic tunnel junction. A pair of complementary bit lines are provided in association with the element. A first access transistor inter-connects a false one of the bit lines to the false node of the latching circuit, while a second access transistor inter-connects a true one of the bit lines to the true node of the latching circuit. The memory element accordingly has an SRAM four transistor (4T) two load (2R) architecture wherein the resistances associated with the two magnetic tunnel junctions provide the two load resistances.
