Multitasking is a new ken of a smartphone memory requirement: DRAM and NAND integration (page 1/2)

　The memory / storage requirements of the smartphone are still deducted by the 5G (5th generation mobile communication) network.However, this 5G network is not the only element that pressure on mobile DRAM and flash memory.

　"With a wide range of bandwidth and speeding up, a new way for a very large size file has been opened by the introduction of 8K videos, including the wide bandwidth and faster, as the head of Western Digital's mobile segment marketing department.This has increased the file size of the video about twice. "

　The company has recently announced the 2nd generation UFS 3.1 storage solution "Inand MC EU551" for 5G smartphones.In addition to games, AR (extended reality) / VR (virtual reality), it will also provide support for various ultra -high resolution cameras for burst mode (Burst mode) photography.This new storage is based on Western Digital for the first time based on the UFS 3.1 platform, and uses high -speed NAND flash memory, controller, and high -performance firmware.

　"Existing smartphones will allow existing smartphones to be able to carry out larger files at a much higher speed. The Inand MC EU551 can increase sequential writing speed by 90 % compared to the old generation.Therefore, not only can you make the most of the advantages of 5G, but also the speed of downloading by Wi-Fi 6 can be realized. Also, by increasing the sequential reading speed by 30 %, standing in a short starting time.It can also be raised or faster uploads. Western Digital makes a higher-speed file with a new Wi-Fi standard that exceeds Wi-Fi 6 with memory and storage.I want to go. "

　"Smartphones are currently required to execute multiple applications at the same time as PCs. The Inand MC EU551 has improved random reading performance and up to 40 % random writing performance.It is possible to support various workload experiences. In addition, with the spread of 5G -compatible devices, smartphones are expanding and resolution continues to be improved so that they can support 8K videos.Currently, 5G is actually starting to grow rapidly. Most of most flagship terminals are now equipped with 5G compatibility, which is an element that reduces the need for high performance of various interfaces."(Mr.)

Multitasking that progresses with an increase in the number of mounted sensors

　In addition, he "The number of sensor devices mounted on the smartphone platform is continuing to increase. It is equipped with an electrostatic capacity sensor, magnetic sensor, acceleration sensor, etc. so that the surrounding environment can be grasped in a new way.Right now, an application that can make good use of these sensor performance is about to appear. These promote multitasking, and the demands for latency will increase. "

　Large -capacity videos taken with a smartphone may be edited on the device.In that case, the writing requirements to the flash storage will increase, and AI (artificial intelligence) will be installed.

　Gilboa said, "The mobile phone manufacturer is looking for a way to differentiate each terminal, not simply advertising a large -capacity storage to users.We are looking for what we do. "It is also said that mobile phone manufacturers may control the data path under various conditions and have a unique function that does not reduce the performance of mobile phones."Now we are at the stage of saturating the ability of the interface" (Gilboa)

　The company's INAND is a buffering technique that improves sequential writing speed, and a post -performance booster (HPB) 2.0, which improves sequential writing speeds, doubles random reading performance, and 40 % random writing performance.It adopts two proprietary functions."These functions will be much more than what they need for their current emerging applications, but they will be normal in one and a half years," said Gilboa.
