Samsung Electronics announced at the 2022 Flash Memory Summit held at the Santa Clara (California) Convention Center that the industry’s first UFS 4.0 mobile storage developed in May is scheduled to enter mass production this month. Samsung says the new UFS 4.0 flash memory will be a key component in flagship smartphones and will be used in mobile, VR, and AR devices in the future.
According to information previously announced by Samsung, Samsung UFS 4.0 flash memory provides a speed of up to 23.2Gbps per channel, which is twice that of Samsung’s predecessor UFS 3.1. UFS 4.0 will deliver sequential read speeds of 4200MB/s and sequential write speeds of 2800MB/s with Samsung’s 7th generation V-NAND technology and proprietary controller.

At the same time, the energy efficiency of UFS 4.0 has also been improved. UFS 4.0 will provide a sequential read speed of 6.0MB/s per mA (milliampere), which is 46% higher than the previous generation. Therefore, with the same power consumption, users can transmit more data.
Samsung noted that for more efficient space utilization and design convenience, UFS 4.0 will be available in a compact package measuring 11mm x 13mm x 1mm and will offer various capacity options up to 1TB. At the 2022 Flash Memory Summit, Samsung also launched a new generation of storage technology “Petabyte Storage”.
This new solution will enable a server unit to fit more than 1PB of storage space, allowing server manufacturers to significantly increase storage capacity with a minimum number of servers in the same floor space. High server utilization will also help. to reduce power consumption. Samsung announced its “Memory-semantic SSD,” which combines the advantages of storage and DRAM memory.
Leveraging Compute Express Link (CXL) interconnect technology and built-in DRAM cache, Memory-semantic SSDs can deliver up to 20x faster random read speeds and latency when used in AI and ML applications. Samsung’s Memory-semantic SSDs are optimized to read and write small-sized data blocks at faster speeds and are officially described as ideal for the growing number of AI and ML workloads that require fast processing of smaller datasets choice.
Samsung also announced information on two enterprise-class SSDs, including the industry’s first PCIe 5.0 SSD, the PM1743, and the first 24G SAS SSD, the PM1653, both of which are now in mass production.
