PMIC works with small outline, un-buffered DDR5-based DIMMs

Integrated Device Technology, Inc. introduced the industry’s first integrated power management IC (PMIC) developed for small outline and un-buffered DDR5-based dual in-line memory modules (DIMM) addressing a broad range of notebook, desktop and embedded computing platforms. IDT’s P8911 enables next-generation client platforms to take full advantage of DDR5 memory to realize greater performance, density and reliability while reducing overall system power. The new PMIC joins the previously announced P8900 PMIC, DDR5 RCD and DDR5 SPD hub to augment the growing family of DDR5 solutions from IDT.

Distributing power management functions across each memory module – as opposed to centralizing them on the motherboard – brings inherent benefits to system thermal profiles, as well as reliability and scalability. The rise of storage class memory with unique voltage, current and power sequencing requirements is also a key trend requiring distributed power architectures.  While servers have taken the lead in adopting this innovative new approach for next-generation equipment, client systems are now following suit as the advantages become even clearer and more compelling.

The IDT P8911 is optimized from the previously announced P8900 server PMIC to meet the specific needs of client and embedded applications. The footprint and power delivery characteristics are tailored for smaller form factor memory modules that reside in systems that may operate on battery power for extended periods. New ultra-low current power states such as quiescent and idle modes can provide significant battery life extension compared to earlier motherboard power solutions. The new PMIC also includes some of the most valuable reliability and serviceability (RAS) features from the server world such as fault protection, error injection, error logging and advanced telemetry.

The new PMIC is released and sampling now.
