    摘要: Systems, circuits and methods for software programmable logic using Spin Transfer Torque Magnetoresistive Random Access Memory (STT-MRAM) technology are disclosed. Magnetic tunnel junction (MTJ) storage elements can be formed into input planes and output planes. The input planes and output planes can be coupled together to form complex arrays that allow for the realization of logic functions.

    摘要: Electronic circuits use latches including a magnetic tunnel junction (MTJ) structure and logic circuitry arranged to produce a selective state in the MTJ structure. Because the selective state is maintained magnetically, the state of the latch or electronic circuit can be maintained even while power is removed from the electronic device.

    摘要: A full-scan latch is provided that may be used to incorporate design for test functionality in an integrated circuit. The full-scan latch includes a shadow latch, a multiplexer, and a slave latch. The full-scan latch has a test mode and a normal mode. When in the normal mode, the device operates as a transparent latch, passing a data input to its output. When in test mode, the device is operable to pass scan data down a scan chain and to inject scan data into the data path.

    摘要: An integrated circuit includes multiple power domains. Supply current switch circuits (SCSCs) are distributed across each power domain. When a signal is present on a control node within a SCSC, the SCSC couples a local supply bus of the power domain to a global supply bus. An enable signal path extends through the SCSCs so that an enable signal can be propagated down a chain of SCSCs from control node to control node, thereby turning the SCSCs on one by one. When the domain is to be powered up, a control circuit asserts an enable signal that propagates down a first chain of SCSCs. After a programmable amount of time, the control circuit asserts a second enable signal that propagates down a second chain. By spreading the turning on of SCSCs over time, large currents that would otherwise be associated with coupling the local and global buses together are avoided.
