  • Patent number: 10332591
    Abstract: Embodiments of the present invention provide systems and methods for re-balancing the stability of a SRAM cell. Embodiments of the present invention identify SRAM cells with negative voltage threshold margins and write a “zero” state bit with in the bi-stable flip-flop of the SRAM. Raising the voltage of the CMOS set containing the “zero” state bit and selective transistor biasing, skews the “zero” state bit towards the complementary “one” state bit. This induces an increase voltage thresholds of the identified SRAM cells.

  • Patent number: 10325646
    Abstract: The disclosure describes approaches for generating a physically unclonable function (PUF) value. Power is applied to a power control circuit, an SRAM, and a PUF control circuit. After initially powering-up the SRAM, the PUF control circuit signals the power control circuit to disable power to the SRAM. The power control circuit disables power to the SRAM, and then re-enables power to the SRAM after having power to the SRAM disabled for a waiting period. The PUF control circuit reads a PUF value from the SRAM by the PUF control circuit after the enabling of power.

    Abstract: Devices and methods for non-volatile analog data storage are described herein. In an exemplary embodiment, an analog memory device comprises a potential-carrier source layer, a barrier layer deposited on the source layer, and at least two storage layers deposited on the barrier layer. The memory device can be prepared to write and read data via application of a biasing voltage between the source layer and the storage layers, wherein the biasing voltage causes potential-carriers to migrate into the storage layers. After initialization, data can be written to the memory device by application of a voltage pulse between two storage layers that causes potential-carriers to migrate from one storage layer to another. A difference in concentration of potential carriers caused by migration of potential-carriers between the storage layers results in a voltage that can be measured in order to read the written data.

    Abstract: A semiconductor integrated circuit device has a memory array including SRAM cells, a plurality of sense amplifiers for reading out data stored in the SRAM cells and a plurality of MOSFETS. The MOSFETs are controlled by a control signal to be in one of an active state or a standby state. Part of the MOSFETs are arranged along one end of the memory array and the other parts of the MOSFETs are arranged along another end of the memory array. The other end of the memory array is opposite to the one end of the memory array. The MOSFETs are controlled by the control signal to be turned ON in the active state and to be turned OFF in the standby mode.

  • Patent number: 9915993
    Abstract: Supply of power to a plurality of circuits is controlled efficiently depending on usage conditions and the like of the circuits. An address monitoring circuit monitors whether a cache memory and an input/output interface are in an access state or not, and performs power gating in accordance with the state of the cache memory and the input/output interface. The address monitoring circuit acquires and monitors an address signal between a signal processing circuit and the cache memory or the input/output interface periodically. When one of the cache memory and the input/output interface is in a standby state and the other is in the access state, power gating is performed on the circuit that is in the standby state.

  • Patent number: 9911481
    Abstract: A selection circuit and related access circuitry that can be used for column selection in spin-torque magnetic memory is disclosed. The selection circuit can be implemented with three transistors, all of which can be NMOS transistors, thereby reducing area requirements. The selection circuit includes drive transistor that can be autobooted based on the drive voltage applied across the drive transistor. A single control signal controls the state of the selection circuit, and the selection circuits can be nested to provide multiple levels of decoding or selection.

  • Patent number: 9905284
    Abstract: A storage device includes a memory cell array, a voltage detector disposed to detect a voltage of power supplied to the memory cell array, and a controller. The controller is configured to carry out reading of data from a target memory cell and then rewriting of the data in the target memory cell, if the detected voltage is above a threshold when a prompt of a read operation with respect to the target memory cell occurs, and prohibit the reading operation from being started, if the detected voltage is below the threshold when the prompt occurs.

  • Patent number: 9899105
    Abstract: Systems and methods for low voltage secure digital (SD) interfaces are disclosed. Embodiments of the present disclosure relate to systems and voltage for a lower voltage SD or SD Input/Output (SDIO) interface such as two integrated circuits. In particular, a SD or SDIO interface may be established between two SD compliant devices. While the SD compliant devices may otherwise comply with the SD standard, the voltage levels for signals passed between the SD compliant devices may be below 1.8 volts that the standard mandates. This reduced voltage is possible because the distances involved for interchip communication or the short distances involved for mobile terminal to peripheral connection are short enough that the reduced voltage is sufficient to still provide the desired signal strength at the receiver.

  • Patent number: 9875787
    Abstract: A memory stack comprises at least two memory components. The memory components have a first data link interface and are to transmit signals on a data link coupled to the first data link interface at a first voltage level. A buffer component has a second data link interface coupled to the data link. The buffer component is to receive signals on the second data link interface at the first voltage level. A level shifting latch produces a second voltage level in response to receiving the signals at the second data link interface, where the second voltage level is higher than the first voltage level.

  • Patent number: 9874912
    Abstract: An energization range of a laptop PC is controlled for safety component replacement. An EC can communicate with a battery unit to control a FET of the battery unit. In a power-off state, a PWC receives electricity from the battery unit or an AC/DC adapter. In the power-off state, a system of the EC stops. When a housing cover of the laptop PC is opened, a cover switch turns ON. When a logic circuit detects the operation of the cover switch, the PWC controls a DC/DC converter group to activate the system. The EC receiving electricity turns the FET OFF. Then the PWC turns the FET OFF.

  • Patent number: 9865334
    Abstract: A voltage supply circuit for a memory cell including a first circuit coupled between a first voltage supply and a first voltage supply terminal of the memory cell, and a second circuit coupled between the first voltage supply and a second voltage supply terminal of the memory cell. The first circuit is controlled by a first bit line of the memory cell, and the second circuit is controlled by a second bit line of the memory cell. The first and second circuits provide the first supply voltage to the first and second voltage supply terminals of the memory cell, respectively, during a pre-charge phase. During a write operation, only one of the first circuit and the second circuit provides the first supply voltage to the memory cell, and the other one of the first circuit and the second circuit provides an adjusted voltage (e.g., a collapsed voltage) to the memory cell.
