Samsung LPDDR5 uMCP Mass-production Started

Recently, Samsung announced that the latest multi-chip package LPDDR5 uMCP for mobile devices started mass production and completed compatibility testing between LPDDR5 uMCP and several domestic smartphone manufacturers. As 5G devices become mainstream and mobile devices equipped with Samsung’s new generation LPDDR5 uMCP chips hit the market, more mid-to high-end smartphone users will feel a smooth experience similar to the performance of flagships.

As we all know, with the proliferation of high-definition pictures, 4K videos, games, and applications such as augmented reality AR and mixed reality MR in the 5G era, users will have an increasingly strong demand for high-capacity, high-performance smartphones. How to improve the performance of smartphones while reducing power consumption, differentiated appearance and internal configuration have been a problem for major cell phone manufacturers.

Samsung’s uMCP multi-chip packaging technology allows more design space for other original components of mobile devices by integrating DRAM and NAND storage in a single chip, occupying a size of only 11.5mm x 13mm. Not only that, the latest mass-produced LPDDR5 uMCP has unparalleled advantages over its predecessor in terms of both performance and power consumption.

The new generation uMCP uses the fastest rate LPDDR5 memory in Samsung products and the industry’s latest UFS 3.1 specification flash memory integrated configuration, in which LPDDR5 DRAM than the previous generation LPDDR4X in performance, performance is about more than 50%, data transfer rate up to 6400Mbps, higher bandwidth advantage, can long cope with the future 5G era of VR/AR and other applications in the future 5G era.

The LPDDR5 DRAM has been tested to increase FPS (Frames Per Second) by 14% when operating at maximum frequency, a figure that allows more smartphone users to experience smooth, high frame rate gaming graphics. In particular, power consumption can be reduced by 20% compared to the previous generation thanks to technologies such as Dynamic Voltage Frequency Regulation (DVFS) and Deep Sleep Mode.

It is worth mentioning that UFS 3.1 applied by Samsung is the latest flash memory standard announced by JEDEC (the microelectronics industry-standard development body) in 2020, which goes further in capturing data with high traffic such as images and videos. In this UFS 3.1 NAND flash update, NAND write speeds are three times faster than its predecessor and bandwidth have been increased from 12Gbps to 24Gbps, doubling performance in its entirety.

Samsung has also embedded Write Booster Technology (TW, Turbo Write), Host Performance Booster Technology (HPB, Host Performance booster), and Host Initiated Defragmentation Technology (HID, Host Defragmentation), which are software technologies that can effectively improve the random read and write performance, accelerate the processing speed of the phone, reduce the lag and the slower use of the situation.

Now, smartphones are facing the transition from 4G to 5G, and having the ability to handle large amounts of streaming media in the 5G era is an inevitable development trend for future smartphones. Samsung’s LPDDR5 uMCP is the solution for mid-range and high-end smartphones to move into the 5G era, meeting the growing market demand for high performance, low power consumption, and high capacity in the future.
