Samsung Electronics Unveils Three PMICs for DDR5 DRAM Modules
S2FPD01 and S2FPD02 for Enterprise,
S2FPC01 for clients, memory performance support


On the 18th, Samsung Electronics unveiled three types of power management ICs (PMICs) that maximize the performance of DDR5 DRAM modules and minimize power usage.

Since Samsung Electronics first entered the PMIC field in 2010, it has been releasing PMICs for mobile products such as smartphones and tablets, as well as PCs, game consoles, and wireless earphones. The latest Samsung Electronics PMICs, 'S2FPD01, S2FPD02, S2FPC01', will be used as semiconductors for DDR5 DRAM modules to enhance DRAM performance and reduce operating power.

Unlike DDR4 DRAM, which had its PMIC mounted on an external substrate, DDR5 DRAM mounts the PMIC directly on the DRAM module substrate. The PMIC and DRAM are housed in a single module, which enables stable and fast power supply, improving memory performance while minimizing malfunctions.

Samsung Electronics applied its own design technology, the 'Asynchronous based dual phase buck control scheme', to detect voltage changes in real time and maintain the output voltage at a constant level. This technology supports stable data read and write speeds of DDR5 DRAM and reduces the use of multilayer ceramic capacitors (MLCCs) that were previously used to maintain a constant voltage, thereby increasing design convenience.

The enterprise PMIC, S2FPD01 and S2FPD02, applies the ‘Hybrid Gate Driver’ that efficiently adjusts the output voltage, improving the power efficiency to 91%, which is 1% higher than the industry standard. In addition, the S2FPC01, which is mounted on the DDR5 DRAM module for clients, applied the low-power 90nm (nanometer) process to reduce the chip area.
