  • Patent number: 11062748
    Abstract: A memory controller includes an interface to receive a data strobe signal and corresponding read data. The data strobe signal and the read data correspond to a read command issued by the memory controller, and the read data is received in accordance with the data strobe signal and an enable signal. A circuit in the memory controller is to dynamically adjust a timing offset between the enable signal and the data strobe signal, and control logic is to issue a supplemental read command in accordance with a determination that a time interval since a last read command issued by the memory controller exceeds a predetermined value.

  • Publication number: 20210081269
    Abstract: A controller includes a link interface that is to couple to a first link to communicate bi-directional data and a second link to transmit unidirectional error-detection information. An encoder is to dynamically add first error-detection information to at least a portion of write data. A transmitter, coupled to the link interface, is to transmit the write data. A delay element is coupled to an output from the encoder. A receiver, coupled to the link interface, is to receive second error-detection information corresponding to at least the portion of the write data. Error-detection logic is coupled to an output from the delay element and an output from the receiver. The error-detection logic is to determine errors in at least the portion of the write data by comparing the first error-detection information and the second error-detection information, and, if an error is detected, is to assert an error condition.

  • Publication number: 20200218686
    Abstract: The timing of the synchronous interface is controlled by a clock signal driven by a controller. The clock is toggled in order to send a command to a memory device via the interface. If there are no additional commands to be sent via the interface, the controller suspends the clock signal. When the memory device is ready, the memory device drives a signal back to the controller. The timing of this signal is not dependent upon the clock signal. Receipt of this signal by the controller indicates that the memory device is ready and the clock signal should be resumed so that a status of the command can be returned via the interface, or another command issued via the interface.

  • Publication number: 20190052105
    Abstract: A method for automatically identifying Apple and Android devices is provided, allowing a mobile charging apparatus to charge a charged device and perform USB data communication. The mobile charging apparatus enumerates the charged device in a USB Host mode to obtain VID information. If the VID information indicates that the charged device is an Apple device, the mobile charging apparatus switches to a USB Device mode, the charged device switches to the USB Host mode, and the charged device performs subsequent USB data communication with the mobile charging apparatus. If the VID information indicates that the charged device is an Android device, the mobile charging apparatus maintains the USB Host mode, the charged device maintains the USB Device mode, and the mobile charging apparatus performs subsequent USB data communication with the charged device. While performing USB data communication, the mobile charging apparatus can also charge the charged device.

  • Patent number: 10180865
    Abstract: A memory device includes a first interface that is to couple to a bidirectional link and a second interface to couple to a unidirectional link. An encoder generates first error-detection information corresponding to write data received via the bidirectional link for a write operation. An encoder generates second error-detection information corresponding to read data transmitted via the bidirectional link for a read operation. A transmitter coupled to the unidirectional link transmits the both the first and second error-detection information. A controller may receive the first and second error-detection information. Based on at least one of the first and second error-detection information, the controller may command the memory device to retry an operation.
