1 Introduction to High Bandwidth Memory

High Bandwidth Memory (HBM) is a JEDEC specification (JESD-235) for a wide, high
bandwidth memory device. The next generation of High Bandwidth Memory, HBM2, is
defined in JEDEC specification JESD-235A. The HBM2 implementation in Intel

The High Bandwidth Memory DRAM is tightly coupled to the host die with a distributed
interface. The interface is divided into independent channels, each completely
independent of one another. Each channel interface maintains a 128-bit data bus,
operating at DDR data rates.

1.1 HBM2 in Intel Stratix 10 MX Devices

Intel Stratix 10 MX incorporates a high-performance FPGA fabric along with a HBM2
DRAM in a single package. Intel Stratix 10 MX devices support up to a maximum of
two HBM2 interfaces.
Intel Stratix 10 MX incorporates Intel's Embedded Multi-Die Interconnect Bridge
(EMIB) technology to implement a silicon bridge between HBM2 DRAM memory and
the Universal Interface Block Subsystem (UIBSS), which contains the HBM2 controller
(HBMC), physical-layer interface (PHY), and I/O ports to interface to the HBM2 stack.
As illustrated below, each Intel Stratix 10 MX device contains a single universal
interface bus per HBM2 interface, supporting 8 independent channels.
The user interface to the HBM2 controller is maintained through the AIX4 protocol.
Sixteen AXI interfaces are available in the user interface from each HBM2 controller,
with one AXI interface available per HBM2 Pseudo Channel. HBM2 DRAM density of
4GB and 8GB are supported.
