For HBM2,it contains two HBM stacks, each stack has eight channels,one channel is divided into two pseudo channels,so each HBM stack has 16 pseudo channels totally. For 4 Hi-stack each PCH provides 2Gbit storage capacity, there are 8 memory controllers in each stack, each of which controls the accesses towards two adjacent PCHs. The switch network is composed of 8 4Ąż4 mini-switches,each of which connects two adjacent MCs and exposes 4 AXI interfaces to the FPGA. Every two adjacent mini-switches are connected with a bus to provide global addressing, such that a memory access towards an arbitrary PC can be issued from any AXI interface.
