CXL.cache – defines interactions between a host and a device, [38] allows peripheral devices to coherently access and cache host CPU memory with a low latency request/response interface. CXL.mem – allows host CPU to coherently access device-attached memory with load/store commands for both volatile (RAM) and persistent non-volatile (flash ...
Development of 3D XPoint began around 2012. [8] Intel and Micron had developed other non-volatile phase-change memory (PCM) technologies previously; [note 1] Mark Durcan of Micron said 3D XPoint architecture differs from previous offerings of PCM, and uses chalcogenide materials for both selector and storage parts of the memory cell that are faster and more stable than traditional PCM ...
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. An OMI ...
SK Hynix shows off 512GB computational memory solution (CMS) with PCIe 4.0/CXL interface.
The MI300A supports PCIe 5.0 and CXL 2.0 interfaces, which allow it to communicate with other devices and accelerators in a heterogeneous system. The MI300X is a dedicated generative AI accelerator that replaces the CPU cores with additional GPU cores and HBM memory, resulting in a total of 304 CUs (64 cores per CU) and 192 GB of HBM3 memory.
The UCIe 1.0 specification was released on March 2, 2022. [5] It defines physical layer, protocol stack and software model, as well as procedures for compliance testing.The physical layer supports up to 32 GT/s with 16 to 64 lanes and uses a 256 byte Flow Control Unit (FLIT) for data, similar to PCIe 6.0; the protocol layer is based on Compute Express Link with CXL.io (PCIe), CXL.mem and CXL ...
The Gen-Z Consortium is a trade group of technology vendors involved in designing CPUs, random access memory, servers, storage, and accelerators.The goal was to design an open and royalty-free "memory-semantic" bus protocol, which is not limited by the memory controller of a CPU, to be used in either a switched fabric or a point-to-point device link on a standard connector.
The last image we have of Patrick Cagey is of his first moments as a free man. He has just walked out of a 30-day drug treatment center in Georgetown, Kentucky, dressed in gym clothes and carrying a Nike duffel bag.
