  • Patent number: 11955169
    Abstract: A multi-port memory is provided that supports collision between a read port and a write port to the same multi-port bitcell. A sense amplifier reads a data bit from a multi-port bitcell when a write port to the multi-port bitcell is addressed during a system clock signal. Should a read port to the multi-port bitcell be addressed during the same system clock signal, a multiplexer selects for an output bit from the sense amplifier.

  • Patent number: 11837313
    Abstract: A memory is provided that is configured to practice a sleep mode without retention in which a both bitcell array and a memory periphery are powered down responsive to an assertion of sleep mode without retention control signal. The sleep mode without retention control signal is also asserted during a DVS scan to power down the bitcell array. The memory includes a power management circuit that responds to an assertion of a DVS scan control signal to prevent the assertion of the sleep mode without retention control signal from causing a power down of the memory periphery during the DVS scan. The memory periphery may thus be thoroughly tested by the DVS scan because leakage current from the bitcell array is prevented by the powering down of the bitcell array.

The method includes receiving definitions associated with microservices related to implementing hardware and software solutions with respect to hardware and software systems. In response, a definition file and associated code comprising the definitions and associated dependencies associated with the microservices are generated. The microservices are deployed to a container orchestration system cluster on a cloud structure and a service mesh and machine learning module are installed within the container orchestration system cluster. Proxies comprising a proxy for each pair of dependencies are generated and network traffic passing through each proxy is monitored. A malfunction of a hardware or software system is detected and an associated network route passing through an associated proxy is disabled.

  • Patent number: 10867668
    Abstract: A memory and method of performing a write operation in a memory are disclosed. In one aspect of the disclosure, the memory includes a memory cell, a pair of bit lines coupled to the memory cell, a multiplexer, and a pull-up circuit coupled to the multiplexer. The multiplexer may be configured to select the pair of bit lines coupled to the memory cell during the write operation. To increase the write performance of the memory cell, the pull-up circuit is configured to select which of the pair of bit lines is a non-zero bit line during the write operation and to clamp the non-zero bit line through the multiplexer to approximately a power rail voltage. Thus, the pull-up circuit may increase the voltage difference between the non-zero bit line and the zero bit line during the write operation and thus decrease the area and power consumed by a boost capacitance.
