    摘要: A memory control component allocates a portion of an auxiliary signaling channel and corresponding memory storage, conventionally dedicated to error correction code (ECC) conveyance and storage, for conveyance of metadata and/or other types of component-level information—splitting the auxiliary channel between metadata and ECC conveyance/storage in proportions that obviate conventional metadata conveyance/storage via the primary data channel and thus maintaining full primary channel bandwidth/storage-capacity for user data.

    摘要: A total number V of virtual host-managed device memory (HDM) decoder configurations are generated for the same total number V of HDM memory regions attached to a non-host computing device. Each virtual HDM decoder configuration in the virtual HDM decoder configurations corresponds to a respective HDM memory region in the HDM memory regions. A proper subset of one or more virtual HDM decoder configurations is selected from among the virtual HDM decoder configurations to configure one or more physical HDM decoders of a total number P of the non-host computing device into one or more virtual HDM decoders. The one or more physical HDM decoders configured as one or more virtual HDM decoders are applied to translate a host physical address (HPA) received from a host computing device in a memory access transaction involving the host computing device and the non-host computing device.

    摘要: A hot-swappable DRAM cartridge implemented in a standards-compliant SSD form-factor has an access panel that opens to enable removal and insertion of socketed DRAM memory modules. In at least some implementations, the DRAM cartridge complies with form-factor, protocol, connector, and pin-out/signal specifications set forth in one or more Enterprise and Data Center Standard Form Factor (EDSFF) specifications promulgated by Storage Networking Industry Association (SNIA) including, for example and without limitation, form-factor specifications set forth in EDSFF standards E3.S, E3.S 2T, E3.L and E3.L 2T.

    摘要: First and second clock signals are generated based on signal transitions within first and second streams of symbols, respectively, received within an integrated circuit component, the first and second clock signals having a time-varying phase offset with respect to one another. A first control circuit, operating in a first timing domain established by the first clock signal, generates first control information based on the first stream of symbols and forwards the first control information, via a domain crossing circuit that bridges the time-varying phase offset, to a second control circuit operating in a second timing domain. The second control circuit generates a third stream of symbols based on the first control information and on the second stream of symbols, and a transmit circuit outputs the third stream of symbols from the integrated circuit component synchronously with respect to the second clock signal.
