Rambus has upgraded its DDR5 PMIC lineup with three new offerings for servers allowing support for better performance and capacities.
DDR5 DRAM For Servers Will Get Better In All Possible Ways With New Rambus PMIC Options, Up To 12V "Extreme Current" Device
Press Release: Rambus, a premier chip and silicon IP provider making data faster and safer, today announced the availability of its new family of state-of-the-art DDR5 server Power Management ICs (PMICs), including an industry-leading extreme current device for high-performance applications. With this new family of server PMICs, Rambus offers module manufacturers a complete DDR5 RDIMM memory interface chipset supporting a broad range of data center use cases.
- I2C and I3C Basic bus serial interface support
- Meets or exceeds all JESD300-5 performance specifications up to 1MHz for I2C and
12.5MHz for I3C Basic bus serial interface - Parity error check and packet error check (PEC) function
- In-band Interrupt (IBI) support
- VIN_Bulk input operational at 4.25V to 15V
- VIN_Mgmt input operational at 3V to 3.6V
- Four step-down switching regulators (SWA, SWB, SWC, and SWD) and
3 LDO regulators (VBias, VOUT_1.8V, VOUT_1.0V) - Write protect and programmable modes of operation
- I2C bus operational at 1.0V to 3.3V nominal I/O levels
- I3C Basic bus operational at 1.0V, 1.1V, and 1.2V nominal I/O levels
- Dynamic driver switching capability for I3C Basic bus operation between push-pull
and open-drain - Operation from -100C to +1250C
- 35-pin thermally enhanced FCQFN package
The PMIC is a critical component in the DDR5 memory architecture, enabling more memory channels, higher capacity modules, and greater bandwidth. The Rambus DDR5 server PMIC family includes products for the JEDEC extreme current (PMIC5020), high current (PMIC5000), and low current (PMIC5010) specifications.
With PMICs on the DDR5 DIMMs, power management is added on an incremental basis that scales with the number of memory modules needed by the system configuration. Another advantage of this power architecture is that it greatly reduces the problem of IR drop on the delivery network by delivering the high voltage 12V supply to the module, as opposed to trying to deliver 1V from the motherboard, through the module connector and onto the memory module. This provides tighter voltage tolerances for the sensitive components on the DIMM, which helps achieve the higher DDR5 performance level targets.
The industry-leading Rambus PMIC5020 will enable future generations of DDR5 RDIMMs delivering new benchmarks for performance and capacity. This new family of Rambus server PMICs, together with Rambus DDR5 RCD, SPD Hub, and Temperature Sensor ICs, comprise a complete memory interface chipset for a broad range of DDR5 RDIMM configurations and use cases. With over 30 years of high-performance memory experience, Rambus offers RDIMM manufacturers a one-stop shop for DDR5 memory interface chips, providing the highest level of validation assurance and speeding time to market.
