Samsung Electronics unveiled three new power management chips that maximize performance and minimize power consumption of DDR5 DRAM modules, the chip giant said Tuesday.
Since the company first launched its power management integrated circuit (PMIC) chips in 2010, Samsung has been releasing PMICs for mobile devices such as smartphones and tablet PCs, as well as other devices, including PCs, gaming consoles and wireless earphones.
The company said that its new power management integrated circuit (PMIC) chips are S2FPD01, S2FPD02 and S2FPC01, and that they will be equipped with DDR5 DRAM modules, providing a more reliable and sustained performance.
DDR5 DRAM is a next-generation type of dynamic random-access memory chip that boasts a faster data transfer speed compared to DDR4 DRAM. Demand for the product will be especially high in the fast-growing market for high-priced servers.
While PMICs for DDR4 DRAM are located on a separate circuit board, new PMICs for DDR5 DRAM will be equipped on the same board for reliable and quick power supply to the DRAM, the company said.
For improved performance efficiency and load-transient responses, Samsung's new PMICs for DDR5 modules have been equipped with a new technology called "asynchronous-based dual-phase buck control scheme." With this technology, the new PMICs are able to detect voltage changes quickly in real-time and keep output voltage constant.
"With enhanced power efficiency and low-output ripple voltage, the new PMICs ― S2FPD01, S2FPD02 and S2FPC01 ― allow data centers, enterprise servers and PC applications to take full advantage of their DDR5 performance for highly demanding, memory-intensive tasks," Harry Cho, vice president of System LSI marketing at Samsung Electronics, said.
Samsung added that the three new products are currently being tested by customers.
Given that PMIC products account for the largest part, around 21 percent, of the power semiconductor device market, Samsung expects its PMIC products to become one of its major cash cows.
Market tracker Omdia said that the PMIC market was scaled at $5.4 billion in 2020 and will grow to $6.9 billion in 2024, growing 6.6 percent on average each year. As of 2019, Samsung's share of the global PMIC market was 6.6 percent.
Industry analysts said that Samsung is expected to release the PMIC products in the fourth quarter of this year and DDR5 DRAM modules in the first quarter of 2022.
