Shulou(Shulou.com)11/24 Report--

Liu Yang, deputy general manager of Baiwei Storage and general manager of embedded business, said: "with the accelerated popularity of 5G communications, big data and AIoT, data-intensive 5G workloads such as games, multi-camera support, AR / VR and high-resolution display require mobile phones to handle growing amounts of data in a short period of time. Relying on its own advantages of research and development of storage solutions and advanced closed testing, Baiwei Storage has launched a uMCP integrated memory chip based on LPDDR5 and LPDDR4X, which takes into account the characteristics of high performance, large capacity and small size, and can meet the growing performance and capacity needs of mobile phones. "

Baiwei's uMCP products based on LPDDR5 integrate LPDDR5 and UFS3.1 memory chips, with sequential read and write speeds as high as 2100MB/s and 1800MB/s, frequency as high as 6400Mbps, capacity as high as 8GB+256GB, and chip size as small as 11.5mm × 13.0mm × 1.0mm. Compared with the separation of UFS3.1 and LPDDR5, it can save 55% motherboard space and help smart phone system design more flexibly.

The reading speed is as high as 2100MB/s, the frequency is up to 6400Mbps, and the power consumption of LPDDR5 is reduced by 30%, which enables the mobile phone to run efficiently and last for a long time.

Compared with the company's LPDDR4X-based uMCP products, Baiwei's LPDDR5-based uMCP products rely on self-developed firmware algorithms and firmware features such as Write booster, SLC Cache, HID, Deep Sleep and other firmware features to improve the reading speed to 2100MB/s. At the same time, Baiwei's uMCP products based on LPDDR5 support multi-Bank Group mode, adopt WCK signal design, etc., the data transmission rate is increased by 50% from 4266Mbps to 6400Mbps, and based on the dynamic voltage regulation (DVFS) function, the VDD2H of LPDDR5 is reduced from 1.1V to 1.05V from 0.6V to 0.5V, and the power consumption is reduced by 30%. With its excellent performance, Baiwei's LPDDR5-based uMCP products can calmly handle large amounts of data and efficiently support smartphone multitasking, high-definition video decoding, game loading, large file copying and other applications.

Capacity up to 8GB+256GB, easy storage of massive data

In real life, the stutter phenomenon will occur after the mobile phone has been used for a long time, especially when taking high-definition photos and opening large video files, the stutter phenomenon is becoming more and more serious, so it is necessary to configure a larger mobile phone storage space. Baiwei's LPDDR5-based uMCP products can provide up to 8GB+256GB capacity (12GB+512GB will be launched in the future) to easily store and process huge amounts of data generated by AIoT, high-speed communications, 8K video, high frame rate games and other applications. In addition, the product provides more SLC cache space to reduce phone stutters due to insufficient write cache for a long time.

Save 55% of the motherboard space, increase the battery capacity of the mobile phone, and make the system more flexible.

Relying on the company's advanced packaging technology such as multi-stack Die and ultra-thin Die, Baiwei uMCP can save 55% of the motherboard space by stacking LPDDR5 and UFS3.1 in one multi-chip stack, helping to simplify the circuit design of the mobile phone motherboard, making room for improving battery capacity and the layout of other parts of the motherboard, realizing more flexible system design of the mobile phone, and helping terminal manufacturers to optimize the BOM list and shorten the shipping cycle.

With the prosperity of short videos, the launch of larger mobile games and the popularity of ultra-high-definition videos such as 4K / 8K, mobile storage continues to evolve in the direction of higher performance, larger capacity and lower power consumption. Relying on the advantage of integrated R & D and closed testing, Baiwei will continue to innovate in smart phones, smart wearable, tablet and other application fields, following the upgrading direction of large memory capacity, large bandwidth, low latency and low power consumption. launch a more competitive storage solution that enables intelligent terminal devices to operate efficiently and stably.

In addition to offering integrated storage solutions such as LPDDR5 / LPDDR4X-based uMCP and eMCP, Baiwei can also provide separate storage solutions such as eMMC5.1, UFS2.2/3.1, LPDDR4x / 5, which can fully meet the storage needs of intelligent terminal devices.
