Jetson Xavier NX integrates a 128-bit wide LPDDR4x memory interface implemented as four 32-bit channels with x16 sub- partitions. The memory controller provides a single read or write command, plus a row address to both sub-partitions in the channel to transfer 64 bytes. It also provides three independent column address bits to each sub-partition, allowing it access different 32-byte sectors of a GOB between the sub-partitions. It provides connections between a wide variety of clients, supporting their bandwidth, latency, quality-of-service needs, and any special ordering requirements that are needed. The MSS supports a variety of security and safety features and address translation for clients that use virtual addresses.
