DDR4 PROTOCOL CHECKS |
JEP175 | Jul 2017 |
The intended use of this document is for the validation and debug of DDR4 based designs. This document contains protocol checks, sometimes referred to as memory access rules or protocol violations. This document contains a list of checks that can be used during the verification or debug stages of development to check that accesses to a DDR4 DRAM adhere to JESD79-4B. These checks are derived from JESD79-4B. Item 31509. Committee(s): JC-40.5 Free download. Registration or login required. |

LRDIMM DDR3 MEMORY BUFFER (MB) |
JESD82-30 | Oct 2014 |
The Load Reduced DIMM (LRDIMM) Memory Buffer (MB) supports DDR3 SDRAM main memory. The Memory Buffer allows buffering of memory traffic to support large memory capacities. Unlike DDR3 Register Buffer (SSTE32882), which only buffers Command, Address, Control and Clock, the LRDIMM Memory Buffer also buffers the Data (DQ) interface between the Memory Controller and the DRAM components. The Memory Buffer interface is responsible for memory requests to and from the local DIMM. LRDIMM provides a high memory bandwidth, large capacity channel solution for DDR3 main memory systems. LRDIMM uses commodity DRAMs isolated from the channel behind the Memory Buffer on the DIMM. Free download. Registration or login required. |

DEFINITION OF THE SSTE32882 REGISTERING CLOCK DRIVER WITH PARITY AND QUAD CHIP SELECTS FOR DDR3/DDR3L/DDR3U RDIMM 1.5 V/1.35 V/1.25 V APPLICATIONS |
JESD82-29A | Dec 2010 |
This standard defines standard specifications of DC interface parameters, switching parameters, and test loading for definition of the SSTE32882 registered buffer with parity for driving address and control nets on DDR3/DDR3L/DDR3U RDIMM applications. The purpose is to provide a standard for the SSTE32882 logic device, for uniformity, multiplicity of sources, elimination of confusion, ease of device specification, and ease of use.

DEFINITION OF THE SSTUB32868 REGISTERED BUFFER WITH PARITY FOR 2R x 4 DDR2 RDIMM APPLICATIONS |
JESD82-26 | May 2007 |

DEFINITION OF SSTU32865 REGISTERED BUFFER WITH PARITY FOR 2R x 4 DDR2 RDIMM APPLICATIONS |
JESD82-9B | May 2007 |
This standard provides the functional definition, ball-out configuration and package outline, signal definitions and input/output characteristics for a 28-bit 1:2 registered driver with parity suitable for use on DDR2 RDIMMs. The SSTU32865 integrates the functional equivalent of two SSTU32864 devices (as defined in JESD82-7) into a single device, thereby easing layout and board design constraints especially on high density RDIMMs such as dual rank, by four configurations. Moreover, the optional use of a parity function is provided for, permitting detection and reporting of parity errors across its 22 data inputs. JESD82-9 specifies a 160-pin Thin-profile, fine-pitch ball-grid array (TFBGA) package. Free download. Registration or login required. |
