High Bandwidth Memory (HBM4) DRAM |
JESD270-4 | Apr 2025 |
The HBM4 DRAM is tightly coupled to the host compute die with a distributed interface. The interface is divided into independent channels. Each channel is completely independent of one another. Channels are not necessarily synchronous to each other. The HBM4 DRAM uses a wide-interface architecture to achieve high-speed, low power operation. Each channel interface maintains a 64 bit data bus operating at double data rate (DDR). The JESD271-4 HBM4 Bump Matrix Spreadsheet will be available in early May. Patents(): There are several patent notifications claims in the JEDEC patent letter spreadsheet file for HBM. I do not know if any of these are going to be asserted against this HBM4 specification but this list is included in the BoD ballot content for reference. Free download.

DDR5 SDRAMRelease Number: Version 1.31 |
JESD79-5C.01 | Jul 2024 |
Version 1.31 This standard defines the DDR5 SDRAM specification, including features, functionalities, AC and DC characteristics, packages, and ball/signal assignments. The purpose of this Standard is to define the minimum set of requirements for JEDEC compliant 8 Gb through 32 Gb for x4, x8, and x16 DDR5 SDRAM devices. This standard was created based on the DDR4 standards (JESD79-4) and some aspects of the DDR, DDR2, DDR3, and LPDDR4 standards (JESD79, JESD79-2, JESD79-3, and JESD209-4).
