    摘要: An I/O interface supports scrambling, where the scrambling can include nonlinear scrambling of the scrambling code, or dynamic bus inversion of the scrambling code, or selective switching of selected bits of the scrambling code, or a combination of these. The transmitting device includes a scrambler and the receiving device includes a descrambler. Both the scrambler and the descrambler generate a linear feedback scrambling code modified by applying one or more of the techniques mentioned above. The modified scrambling code may cause fewer than half of the scrambled output bits to be toggled with respect to a previous scrambled output. The scrambler applies the modified scrambling code to a signal to transmit. The descrambler applies the modified scrambling code to a received signal.

    摘要: A memory controller issues a targeted refresh command. A specific row of a memory device can be the target of repeated accesses. When the row is accessed repeatedly within a time threshold (also referred to as “hammered” or a “row hammer event”), physically adjacent row (a “victim” row) may experience data corruption. The memory controller receives an indication of a row hammer event, identifies the row associated with the row hammer event, and sends one or more commands to the memory device to cause the memory device to perform a targeted refresh that will refresh the victim row.
