    Abstract: A non-uniform switching based non-volatile magnetic memory element includes a fixed layer, a barrier layer formed on top of the fixed layer, a first free layer formed on top of the barrier layer, a non-uniform switching layer (NSL) formed on top of the first free layer, and a second free layer formed on top of the non-uniform switching layer. Switching current is applied, in a direction that is substantially perpendicular to the fixed layer, barrier layer, first free layer, non-uniform switching layer and the second free layer causing switching between states of the first free layer, second free layer and non-uniform switching layer with substantially reduced switching current.

    Abstract: A system and method of generating an output signal of very precise frequency without the use of a crystal oscillator. An input signal is generated using any convenient such as an RC oscillator. A circuit for producing a frequency-controlled output signal comprises a phase lock loop having a VCO and a down counter. The down counter reduces the frequency of a VCO clock signal in accordance with a down count value. The down count value is loaded in a register and stored in non-volatile memory. The down count value is set during a calibration operation using a precision external clock signal. In this way, a clock signal with a highly precise frequency is generated without using a crystal oscillator.

    Abstract: A flash-RAM memory includes non-volatile random access memory (RAM) formed on a monolithic die and non-volatile page-mode memory formed on top of the non-volatile RAM, the non-volatile page-mode memory and the non-volatile RAM reside on the monolithic die. The non-volatile RAM is formed of stacks of magnetic memory cells arranged in three-dimensional form for higher density and lower costs.
