Advanced and innovative features of DDR4 designs enable high speed operation and broad applicability in a variety including servers, laptops, desktop PCs and consumer products. It aims at simplifying migration and enabling adoption of an industry-wide standard.

2. DDR4 Memory
• Advanced and innovative features of DDR4 designs enable high
speed operation and broad applicability in a variety including
servers, laptops, desktop PCs and consumer products. It aims at
simplifying migration and enabling adoption of an industry-wide
standard.
• The device architecture is an 8n prefect with two or four
selectable bank groups. It allows DDR4 memory devices to have
separate activation, read, write or refresh operations with
unique bank group. It improves overall memory efficiency and
bandwidth, especially with small memory granularities.

4. Benefits
Gaming systems:
Performance edge is what gamers want. DDR4 performance
memory unlocks next-gen memory performance and increases
responsiveness and frame rates for a better in-game
experience. Faster speed is achieved with lower latencies than
standard DDR4 modules, pushing the limits with stylized heat
spreaders.

5. Benefits
Desktops & workstations:
Improved speed, bandwidth, and capacity is the demand of
most workstations. With Crucial DDR4 memory, double a
desktop's installed memory capacity is provided, increasing
bandwidth up to 50%, and running applications faster.
Handling data-intensive programs with ease and achieve more.

6. Benefits
Ultra books, laptops, and tablets:
Battery life in mobiles is limited and even the amount of
memory that can be installed. To sort the issue, DDR4 memory
consumes less power and packs more performance into every
module.
