WIDE I/O SINGLE DATA RATE (WIDE I/O SDR) |
JESD229 | Dec 2011 |
This standard defines the Wide I/O specification, including features, functionality, AC and DC characteristics, packages, and micropillar signal assignments. This standard covers the following technologies: Wide I/O. The purpose of this standard is to define the minimum set of requirements for JEDEC compliant, 1 Gb through 32 Gb SDRAM (monolithic density) devices with 4, 128b wide channels using direct chip-to-chip attach methods between 1 to 4 memory devices and a controller device. Free download. Registration or login required. |

WIDE I/O 2 (WideIO2) |
JESD229-2 | Aug 2014 |
This standard defines Wide I/O 2 (WideIO2), including features, functionality, AC and DC characteristics, packages, and micropillar signal assignments. The purpose of this standard is to define the minimum set of requirements for JEDEC compliant, 8 Gb through 32 Gb SDRAM devices with 4 or 8 64-bit wide channels using direct chip-to-chip attach methods for between 1 and 4 memory devices and a controller/buffer device. The WideIO2 architecture is an evolution of the WIO architecture to enable bandwidth scaling with capacity. Committee(s): JC-42.6 Free download. Registration or login required. |

SPECIALITY DDR2-1066 SDRAM |
JESD208 | Nov 2007 |
This document defines the Specialty DDR2-1066 SDRAM specification, including features, functionalities, AC and DC characteristics, packages, and ball/signal assignments. The purpose of this Specification is to define the minimum set of requirements for JEDEC compliant 256 Mb through 4 Gb for x4, x8, and x16 Specialty DDR2-1066 SDRAM devices. Committee(s): JC-42.3 Free download. Registration or login required. |

Serial NOR Security Hardware Abstraction Layer |
JESD261 | Nov 2022 |
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. Committee(s): JC-42.4 Free download.
