  2. High Bandwidth Memory - Wikipedia

    en.wikipedia.org/wiki/High_Bandwidth_Memory

    High Bandwidth Memory (HBM) is a computer memory interface for 3D-stacked synchronous dynamic random-access memory (SDRAM) initially from Samsung, AMD and SK Hynix.It is used in conjunction with high-performance graphics accelerators, network devices, high-performance datacenter AI ASICs, as on-package cache in CPUs [1] and on-package RAM in upcoming CPUs, and FPGAs and in some supercomputers ...

  3. Coherent Accelerator Processor Interface - Wikipedia

    en.wikipedia.org/wiki/Coherent_Accelerator...

    OpenCAPI Memory Interface (OMI) is a serial attached RAM technology based on OpenCAPI, providing low latency, high bandwidth connection for main memory. OMI uses a controller chip on the memory modules that allows for technology agnostic approach to what is used on the modules, be it DDR4 , DDR5 , HBM or storage class non-volatile RAM .

  4. RLDRAM - Wikipedia

    en.wikipedia.org/wiki/RLDRAM

    Reduced Latency DRAM (RLDRAM) is a type of specialty dynamic random-access memory (DRAM) with a SRAM-like interface originally developed by Infineon Technologies.It is a high-bandwidth, semi-commodity, moderately low-latency (relative to contemporaneous SRAMs) memory targeted at embedded applications (such as computer networking equipment) requiring memories that have moderate costs and low ...

  5. HyperTransport - Wikipedia

    en.wikipedia.org/wiki/HyperTransport

    With the advent of version 3.1, using full 32-bit links and utilizing the full HyperTransport 3.1 specification's operating frequency, the theoretical transfer rate is 25.6 GB/s (3.2 GHz × 2 transfers per clock cycle × 32 bits per link) per direction, or 51.2 GB/s aggregated throughput, making it faster than most existing bus standard for PC ...

    Each tile's memory controller provides two channels of DDR5 ECC supporting 4 DIMMs (2 per channel) and 1 TB of memory with a maximum of 8 channels, 16 DIMMs, and 4 TB memory across 4 tiles [33] A tile provides up to 32 PCIe 5.0 lanes, but one of the eight PCIe controllers of a CPU is usually reserved for DMI , resulting in a maximum of 112 non ...

  7. RDMA over Converged Ethernet - Wikipedia

    en.wikipedia.org/wiki/RDMA_over_Converged_Ethernet

    Network-intensive applications like networked storage or cluster computing need a network infrastructure with a high bandwidth and low latency. The advantages of RDMA over other network application programming interfaces such as Berkeley sockets are lower latency, lower CPU load and higher bandwidth. [6]

    High bandwidth memory (HBM) are basically a stack of memory chips, small components that store data. They can store more information and transmit data more quickly than the older technology ...

  9. GDDR7 SDRAM - Wikipedia

    en.wikipedia.org/wiki/GDDR7_SDRAM

    GDDR7 SDRAM employs three-level (-1, 0, +1) pulse-amplitude modulation (PAM-3) instead of NRZ in GDDR6 and PAM-4 in GDDR6x. PAM-3 enables the transfer of three bits of data within two cycles, while NRZ transfer of one bits of data within one cycle. PAM-3 is 20% more energy-efficient than NRZ while running at a higher bandwidth.
