JEDEC Updates Standards for Low Power Memory Devices

ARLINGTON, Va.–(BUSINESS WIRE)–JEDEC
Solid State Technology Association
, the global leader in standards
development for the microelectronics industry, today announced the
publication of JESD209-4B,
Low Power Double Data Rate 4 (LPDDR4) and JESD209-4-1,
Addendum No. 1 to JESD209-4, Low Power Double Data Rate 4X (LPDDR4X).
Both mobile memory standards are designed to significantly boost memory
speed and efficiency for mobile computing devices such as smartphones,
tablets, and ultra-thin notebooks. Developed by JEDEC’s JC-42.6
Subcommittee for Low Power Memories, these documents are available for
free download from the JEDEC
website
.

This latest revision of LPDDR4 offers several updates intended to
achieve even higher performance over the previous version of the
standard, including:

  • Addition of a single-channel die option for smaller applications
  • Addition of new MCP, PoP and IoT packages
  • Additional definition and timing improvements for the highest 4266
    Mbps speed grade

The new LPDDR4X standard is an optional extension intended to offer
product designers options for further power reduction as well as on die
termination (ODT) flexibility. In LPDDR4X, the I/O supply voltage (VDDQ)
is reduced from 1.1 V to 0.6 V. This 40% voltage reduction leads to much
lower power usage when sending and receiving data from the memory
device, which is particularly beneficial for smartphones and other
handheld devices. In addition, LPDDR4X supports easily programmable
command bus termination for high memory density systems.

“The demand for memory solutions that will enable mobile devices to
offer greater performance with lower power usage continues to grow, and
JEDEC remains committed to developing and modifying our standards to
meet these performance expectations,” said Mian Quddus, JEDEC Board of
Directors Chairman.
