The IPA-PM185-CT, code name “Cobra,” is a Gen-Z Hybrid Memory controller that combines both DRAM and NAND in a persistent memory environment. The “Cobra” controller, which sits directly on the Gen-Z fabric and not the memory bus, has the ability to support byte addressability to DRAM cache and Block addressability to NAND flash. Similar to NVDIMM-P type products in function but in different form factors, such as 2.5” and supports much higher capacities. The Cobra product is capable of supporting capacities of up to 32GB of DRAM and 3TB of NAND. Multiple MLC/SLC/TLC and 3D NAND types, ONFI and Toggle are supported today.
