Micron Technology ships first samples of Hybrid Memory Cube
Micron Technology announced today that it is shipping 2GB Hybrid Memory Cube (HMC) engineering samples. HMC uses advanced through-silicon vias (TSVs)—vertical conduits that electrically connect a stack of individual chips—to combine high-performance logic with Micron’s state-of-the-art DRAM. Micron’s HMC features a 2GB memory cube that is composed of a stack of four 4Gb DRAM die. The solution provides an unprecedented 160 GB/s of memory bandwidth while using up to 70 percent less energy per bit than existing technologies, which dramatically lowers customers’ total cost of ownership (TCO).
HMC represents a dramatic step forward in memory technology, and these engineering samples are the world’s first HMC devices to be shared broadly with lead customers. HMC is designed for applications requiring high-bandwidth access to memory, including data packet processing, data packet buffering or storage, and computing applications such as processor accelerators. Micron expects future generations of HMC to migrate to consumer applications within three to five years. Micron expects 4GB HMC engineering samples to be available in early 2014 with volume production of both the 2GB and 4GB HMC devices beginning later in 2014.
