    摘要: A memory controller, memory device, and method for dynamic supply voltage scaling in a memory system are provided. The method includes receiving a request for a supply voltage change at the memory controller in the memory system, the supply voltage powering the memory device. The method further includes waiting for any current access of the memory device to complete, and disabling a clock between the memory controller and the memory device. The method also includes changing the supply voltage responsive to the request, and enabling the clock.

    摘要: A system for providing read clock sharing between memory devices. The system includes a memory device having an external clock receiver, a read clock receiver, and a phase comparator. The phase comparator synchronizes an internal read clock generated at the memory device. The phase comparator additionally synchronizes one of an external clock received by the external clock receiver and an external read clock received by the read clock receiver. The results of the synchronizing are utilized to refresh the internal read clock. The memory device also includes a mechanism, a read clock driver and a mode register fit. The mechanism is utilized to select between the external clock and the external read clock as input to the phase comparator. The read clock driver outputs the internal read clock generated at the memory device to a read clock output pin. The mode register bit controls the selection of the mechanism, the enabling and disabling of the read clock receiver and the enabling and disabling of the read clock driver.

    摘要: A method and circuit for implementing synchronized memory activities of multiple memory devices being accessed in parallel, and a design structure on which the subject circuit resides are provided. Each memory circuit generates an internal status signal for predefined internal memory activities and provides an output signal coupled to the multiple memory devices. Each memory circuit monitors the generated internal status signal and the output signal of at least one of the multiple memory devices, and responsive to the monitored signals generates a control signal for adjusting operation of its memory activities to synchronize memory activities of the memory devices.

    摘要: A system and method for providing a memory device having a shared error feedback pin. The system includes a memory device having a data interface configured to receive data bits and CRC bits, CRC receiving circuitry, CRC creation circuitry, a memory device pad, and driver circuitry. The CRC receiving circuitry utilizes a CRC equation for the detection of errors in one or more of the received data and the received CRC bits. The CRC creation circuitry utilizes the CRC equation for the creation of CRC bits consistent with data to be transmitted to a separate device bits. The memory device pad is configured for reporting of any errors detected in the received data and the received CRC bits. The driver circuitry is connected to the memory device pad and merged with one or more other driver circuitries resident on one or more other memory devices into an error reporting line.
