Samsung 16Gb LPDDR5 RAM mass-produced for next year’s 5G flagships

Although Samsung’s smartphone business has seen a sharp decline in the past two quarters, its semiconductor and silicon business is still going strong. As if to prove that it’s stronger than ever, the company is announcing the mass production of what it boasts to be its most advanced DRAM yet. While the 16Gb (Gigabit, not Gigabyte) capacity alone is already its largest, it’s the production of the chip that Samsung is even more proud of.
For one, it is produced in Samsung’s Pyeongtaek Line 2, which it touts to be the largest-scale semiconductor production line. This is, to some extent, a show of independence and nationalism, reassuring customers that it is able to produce high-quality, high-volume chips from its own home town, outside of foreign locations where Samsung has no direct control.
This third-gen 10nm class (1z) 16Gb V-NAND is also Samsung’s first chip to be mass-produced using EUV or Extreme Ultraviolet lithography. In a nutshell, this method utilizes lasers and light-sensitive chemicals to etch the circuits in the thinnest and smallest sizes possible. The result is a chip that is 30% thinner than the 12Gb DRAM Samsung recently launched.
Despite being smaller, the 16Gb LPDDR5 promises to be even faster, averaging at 6,400 Mb/s (Megabits per second). In ideal situations, that means it can transfer 51.2GB of data, equivalent to ten 5GB full HD movies, in just a second.
Samsung plans to combined just eight of these 16Gb chips to form a 16GB (Gigabyte) RAM package, hinting that it will be packing that module into its 2021 premium phones. Samsung also has its eyes set on automotive applications, however, where it is testing the chip’s reliability to meet environmental standards set by carmakers and regulators.

Jeep’s Wild Wrangler Magneto 3.0 Concept EV Is Going Out With A Bang

To go with that, Jeep has added Dynatrac 60 front axles (5.38:1 ratio) and Dynatrac 80 rear axles (5.38:1 ratio), along with 20-inch off-road beadlock wheels and 40-inch mud terrain tires. The whole thing is lifted by three inches compared to a standard Wrangler. The result, the automaker says, is an EV that excels in off-road situations, not least because of how controllable the power delivery is.
“When you’re rock crawling, you need to be very neat and clean with your driving,” Mike Allen, Jeep Design Chief, says, “especially if there’s a cliff next to you, you need to be very controlled with that.”
To help, Jeep has added a power selection switch. On the one hand, you can have the maximum 650 horsepower and 900 lb-ft of torque; alternatively, the standard setting tamps it down to a more conservative 285 horsepower and 273 lb-ft. Allen says the range is around 150 miles, though that — nor charging times —was never meant to be the Magneto concept’s focus.

The Best Mods & Upgrades That Can Give New Life To A C4 Corvette

Replacing your restrictive and likely corroded factory exhaust with a new cat-back exhaust is one of the best power adders that you can do to your C4 Corvette. The term “cat-back” refers to the section of the system that is downstream of the catalytic converter, a device that removes harmful emissions from exhaust gases.
An aftermarket exhaust with modern muffler technology will reduce backpressure, allowing more air to flow into the engine, which increases horsepower. According to the popular aftermarket exhaust manufacturer Corsa, a cat-back system for the L98 engine (the most common C4 engine) adds 14 horsepower and 16 foot-pounds of torque to an otherwise stock powerplant — all while adding a deep, muscular exhaust note that’ll make your C4 sound like a Corvette should.
Returning to catalytic converters for a moment, they’re typically long-lasting but may eventually fail by becoming contaminated, clogged, or overheated, leading to decreased horsepower. In the process of installing a cat-back exhaust, it’s worth inspecting or proactively replacing the catalytic converter itself. High-flow performance converters are available which will boost horsepower beyond the cat-back exhaust alone, yet still keep your vehicle compliant with the emissions guidelines of the EPA and local authorities.

6 Easy Ways To Unlock Your Android Phone Without A Password

For years, fingerprints have been the de-facto phone unlock method because of the method’s incredible convenience and relative security. While a bad actor can, in theory, replicate your fingerprint, and while some Android phones have had fingerprint reader bugs, the majority of the time it’s secure enough to trust while allowing you to access your device in less than a second.
Many modern Android phones utilize an under-display fingerprint sensor that uses either an optical light sensor or ultrasonics to analyze registered fingerprints, while others place a trusty capacitive sensor on the back of the phone or the power button.
Importantly, optical sensors are the easiest of the three to fool in the event someone gets access to your fingerprint. Law enforcement can be especially aggressive should they invent a reason to search your device, having once tried to use a dead man’s finger to do so. However, Android stores fingerprint data in a Trusted Execution Environment, an encrypted section of the phone’s memory that cannot be accessed by the main CPU or by apps.
Setting your fingerprints up can be a bit of a hassle, as some Android phones can be finicky. It may be a good idea to register the same fingerprint twice if you find that your phone’s fingerprint sensor has a hard time recognizing your preferred digit.
