 Terminology update.This standard defines standard specifications of DC interface parameters, switching parameters, and test loading for definition of the SSTUB32865 registered buffer with parity for 2 rank by 4 or similar high density DDR2 RDIMM applications. The SSTUB32865 is identical in functionality to the SSTU32865 but specifies tighter timing characteristics and a higher application frequency of up to 410 MHz.

Terminology update.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 (see Note) logic device, for uniformity, multiplicity of sources, elimination of confusion, ease of device specification, and ease of use.

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.

Terminology update.  This standard defines standard specifications of DC interface parameters, switching parameters, and test loading for definition of the SSTUA32S869 and SSTUA32D869 registered buffer with parity for driving heavy load on high-density DDR2 RDIMM applications. A typical application would be a 36 SDRAM planar DIMM. The SSTUA32S869 and SSTUA32D869 are identical in functionality to the SSTU32S869 and SSTU32D869 devices respectively but specify tighter timing characteristics and a higher application frequency of up to 410MHz.

This standard describes the serial presence detect (SPD) values for all DDR5 memory modules. In this context, “modules” applies to memory modules like traditional Dual In-line Memory Modules (DIMMs) or solder-down motherboard applications. The SPD data provides critical information about all modules on the memory channel and is intended to be used by the system's BIOS in order to properly initialize and optimize the system memory channels.

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 covers the I-test and Vsupply overvoltage latch-up testing of integrated circuits. The purpose of this standard is to establish a method for determining IC latch-up characteristics and to define latch-up detection criteria. Latch-up characteristics are extremely important in determining product reliability and minimizing No Trouble Found (NTF) and Electrical Overstress (EOS) failures due to latch-up. This test method is applicable to NMOS, CMOS, bipolar, and all variations and combinations of these technologies. This standard has been adopted by the Defense Logistics Agency (DLA) as project 5962-1880.

This standard describes SPI bus transactions intended to support Secure Flash operation on a serial memory device. The on-chip SFDP database described in JESD216 has been revised to include details about the secure transactions. This ballot does not describe the SFDP revisions or the secure packet structure.
