The IPA-GZ194A-CT, code name “Mamba,” is a Gen-Z Fabric DRAM Memory
Controller that provides scalable memory centric, low latency, high bandwidth DRAM memory to the host as volatile storage media. The “Mamba” device sits on the Gen-Z fabric as opposed to the DDR4 memory bus providing scaling flexibility not possible on the memory bus. The streamlined Gen-Z protocol stack also allows for high bandwidth and low latency throughput. Additionally, multiple data masters (CPU) can directly access the Mamba device through a Gen-Z switch allowing data provisioning and data sharing between CPUs. The IPA-GZ194A-CT contains a multi-channel memory controller supporting DRAM capacities up to 768GB using 3DS DRAM components and has the available bandwidth to saturate the Gen-Z Fabric.
