The Versal HBM family contains up to two HBM2e memory stacks of 8 or 16 GB each and an integrated AXI HBM controller for each of the eight memory channels in the stack. Each controller is divided into two semi-independent 64-bit pseudo channels which address a dedicated portion of the HBM. The controller and PHY operate at up to 1600 MHz for a transfer rate of 3200 MT/s. With 128 bits per channel, eight channels per stack, and two stacks in most devices, this yields a maximum throughput of 819 GB/s.
