Samsung has completed the development and testing of a new memory module standard LPDDR5. The chip is created using a 10-nanometer process technology and has a capacity of 8 GB. LPDDR5 DRAM is planned to be used in the production of smartphones with support for mobile communication 5G, on-board electronics of cars, as well as solutions for AI based on mobile platforms.

One of the innovations of LPDDR5 technology is improved energy efficiency. According to the company, the chip consumes 30% less electricity compared to the previous generation of LPDDR4X memory chips. The number of memory banks (subsections of the DRAM cell) is increased from 8 to 16 to provide high speed with low power consumption. In active mode, the module lowers the operating voltage to synchronize with the application processing speed.

Also, the new chip implements an advanced "deep sleep mode" to reduce the power consumption level to half the level of "standby" in LPDDR4X memory modules.

In the new LPDDR5 chip, the data transfer rate is increased to 6400 Mbit / s, which is 1.5 times more than the last LPDDR4X chips. According to Samsung, the module allows to transfer the volume in 51.2 GB of data (14 films with the size of 3.7 GB each as a Full-HD) in just 1 second.

The chip is scheduled to be launched in mass production as soon as the LPDDR5 specification is approved.

AI to Recognize Text Written by Invisible Keyboard

Developers said they tried to increase the typing speed on the on-screen keyboards

Korean developers have created an algorithm that recognizes text printed on an imaginary keyboard on a touchscreen. Such a “keyboard” is not tied to a specific area on the screen, and the “keys” are not limited to clear squares.

As a result, a person types blindly in a QWERTY layout without thinking about where the keyboard should be and whether it got into the key.

According to the developers, they tried to increase the typing speed on the on-screen keyboards. The on-screen keyboard, unlike the hardware keyboard, does not offer feedback that confirms pressing. There is a risk to miss and not press the desired button. Because of this, people endlessly stare at the screen and eventually print more slowly.

The new algorithm allows you not to worry about this, you can enter text from memory, and the keyboard with 96% accuracy will guess what the person wanted to say. Tests have shown that the average typing speed on an imaginary keyboard is slightly less than on a hardware keyboard: 45 words per minute versus 51.
