The HBM3 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 HBM3 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).

This standard provides a comprehensive definition of the NOR cryptographic security hardware abstraction layer (HAL). It also provides design guidelines and reference software to reduce design-in overhead and facilitate the second sourcing of secure memory devices. It does not attempt to standardize any other interaction to the NOR device that is not related to cryptographic security functionality within the device.

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). Item 1848.99M.

This standard was jointly developed by JEDEC and the Open NAND Flash Interface Workgroup, hereafter referred to as ONFI. This standard defines a standard NAND flash device interface interoperability standard that provides means for system be designed that can support Asynchronous SDR, Synchronous DDR and Toggle DDR NAND flash devices that are interoperable between JEDEC and ONFI member implementations.

This document defines the DDR4 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 2 Gb through 16 Gb for x4, x8, and x16 DDR4 SDRAM devices. This standard was created based on the DDR3 standard (JESD79-3) and some aspects of the DDR and DDR2 standards (JESD79, JESD79-2). Committee Item 1716.78H

This document defines the LPDDR4 standard, 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 a JEDEC compliant 16 bit per channel SDRAM device with either one or two channels. LPDDR4 dual channel device density ranges from 4 Gb through 32 Gb and single channel density ranges from 2 Gb through 16 Gb. This document was created using aspects of the following standards: DDR2 (JESD79-2), DDR3 (JESD79-3), DDR4 (JESD79-4), LPDDR (JESD209), LPDDR2 (JESD209-2) and LPDDR3 (JESD209-3).
