The Future of Smartphone Storage Explained

In this article, we’ll discuss the latest advances in smartphone storage, including UFS 4.0, 7th-generation V-NAND, Service Access Points (SAPs), and 7G memory. Listed below are some of the most important new features coming to the smartphone market in 2019.

UFS 4.0

Samsung has just announced the latest smartphone storage standard, UFS 4.0. The new standard is expected to significantly increase the performance of mobile devices, especially those with high-resolution screens. It is also expected to boost battery life since it is 46% faster than UFS 3.1. But what exactly is UFS 4.0? Let’s take a look at its key benefits. First, it offers better read and write speeds. That should make for a more comfortable user experience on the smartphone. Moreover, the improved read and write speeds should be beneficial for emerging technologies such as augmented reality.

7th-generation V-NAND

Samsung is introducing UFS 4.0, the latest standard for Universal Flash Storage. According to the global organization JEDEC, UFS 4.0 has twice the read/write speed of its predecessor and uses 7th-generation V-NAND, a type of memory chip developed by Samsung. The new chip also features an in-house controller to enhance the speed of data processing. In a smartphone, UFS 4.0 is expected to increase the storage capacity by up to 500 percent.

The increased bandwidth of UFS 4.0 should translate into longer battery life for smartphones. The technology is still very new, and it will likely start in flagship devices such as the Samsung Galaxy S lineup, where manufacturer margins are typically higher. However, it will be possible to expect UFS 4.0 to make its way to more mid-range smartphones by early 2023. And it may even take a bit longer than that to reach widespread adoption. The 2023 flagship smartphones will most likely have UFS 4.0 storage chips.

Service Access Points for higher layers

The present disclosure provides a device that can be used to store and manage data, in particular, images, video, music, and other media. Such a device is known as an access point. This device allows users to connect to a smartphone’s storage via a data cable. Generally, a smartphone has a 512 MB storage space. But this size is limited by the number of external devices on a single SIM card. In these cases, a larger device may be needed.


Samsung, a leader in mobile technology, announced plans to include UFS 4.0 storage in its upcoming flagship series in 2023. This new type of storage offers higher sequential read and write speeds, and is expected to be 46% more power-efficient than its predecessor. The new type of storage also promises to improve battery life, thanks to its increased bandwidth. With a maximum bandwidth of 23.2 Gbps per lane, UFS 4.0 will be an excellent addition to your next smartphone.
