Conventions MiB = Megabytes (2^20 bytes) Gb = Gigabits (2^27 bytes, or 128MiB) GiB = Gibibytes (2^30 bytes) Background on HBM2 HBM2 is a type of stacked memory, with each stack containing multiple DRAM dies (chips), and each die supporting 2 channels. Every channel accesses a different (and independent) set of DRAM banks - as a result, requests for one channel cannot access data from another channel. This can be thought of as each channel “owning” a certain address range. Channels may be clocked...
