    摘要: An apparatus and method are disclosed for protecting the contents of a shared memory in a memory device controlled by an embedded controller. The apparatus allows dynamic setting of access permissions to said contents and allows updating and recovery of the contents. A computerized system comprising at least one Host linked to the memory device provides access paths to the shared memory, to the Host, and to the embedded controller. An arbitration device for allocating access paths to the memory device is also provided. The memory device is partitioned into separate blocks, each of which is used to store different types of data. A location is designated in the shared memory for storing protection information that includes data related to access operations allowed by at least one access path to a part of the shared memory. Access, via the arbitration device, to separate parts of the shared memory is permitted by using an access control unit that enables/disables access to predetermined portions of the hared memory by at least one of the access paths.

    摘要: A memory device includes one or more memory arrays and an interface controller for exchanging memory contents data with a semiconductor device over a communication link. The exchanging of data occurs within sequential transactions. Each transaction is associated with a block of consecutive memory locations and with a starting address. The interface controller includes at least two address buffers, each for storing any of the starting addresses and any address obtained by incrementation thereof.

    摘要: In a computer system that includes processing, memory and I/O modules and ACPI for outputting an ONCTL signal to a power supply unit. The power supply is configured to output a power off signal indicative of power off state and power on signal indicative of power on state. There is provided an embedded controller coupled to the ACPI and to the power supply unit. The embedded controller includes input for receiving a shut off event and in response to the shut off event, feeding to the ACPI a controller power off signal as long as the power supply is in power on state.

    摘要: A regulator circuit, embedded in a device, which is adapted to draw power from a power source internal to the device and a power source external to the device. The regulator circuit includes a first circuit segment for regulating power supplied by the internal power source, a second circuit segment for regulating power supplied by the external power source, an output circuit segment that monitors the output of the regulator circuit and supplies regulated power to the device. Additionally, responsive to the monitoring the regulator circuit preferentially draws power from the second circuit segment and complements the drawn power with power from the first circuit segment to maintain a regulated power supply at the output.
