Feeding the beast In-Vehicle Infotainment (IVI) systems have a huge appetite for data storage capacity with mapping and navigation, music and entertainment occupying a growing memory footprint in cars. Up until recently, the car maker’s choice of high-capacity data storage technology was the familiar Hard Disk Drive (HDD), but reliability and lifetime concerns have seen it fall out of favour to be replaced in modern designs by the solid-state drive (SSD) or embedded Multimedia Card (eMMC). Certainly the solid-state solution for data storage is inherently better su...

Efficient 40nm process technology and power-saving innovations minimize energy consumption in all modes Features Arm® embedded core and advanced cybersecurity, graphics, and peripherals for demanding consumer and industrial applications Geneva, February 25, 2021 – STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, has announced a new generation of extreme power-saving microcontrollers (MCUs), the STM32U5* series, to meet the most demanding power/performance requirements for smart applications including wearabl...

Read-Modify-Write Core The Read-Modify-Write (RMW) Core from Rambus handles misaligned bursts when an Error Correction Code (ECC) is being used. An ECC code word must be calculated over an entire data word. Misaligned bursts can have partial data words at the front and back end of the burst. To calculate the correct ECC code word, the Read-Modify-Write Core forms the correct starting and ending data words by reading the existing data words and combining them appropriately with the new partial data words. The core performs address translation from byte addressing to the 64-bit or 128-b...

By Shine Chung, Chairman of Attopsemi™ Technology Abstract: OTP stands for “One-Time Programmable”, a device that can only be programmed once to store data permanently but ideally read infinite times. Traditionally, testability has been an issue for OTP. Every OTP bit should be programmed to ensure programmability. However, if only a single bit is programmed, the OTP block can no longer be used. Patented by Attopsemi™, I-fuse™ is a revolutionary non-breaking fuse technology that can be reliably programmed by heat assisted electromigration below a break point. Any cell can be tested...

Consumer DDR5 RAM is coming in 2021 In the hardware world, we’ve gone through generations upon generations of graphics cards and processors, but we’re still rocking the same DDR4 RAM technology that has been in the best gaming PCs for the past six years. Although RAM isn’t the most exciting of topics, the arrival of DDR5 this year should be welcomed, with big performance improvements. Memory manufacturer TeamGroup has plans to initially release a single 16GB DDR5 stick for consumers with a frequency of 4,800MHz, a big improvement over what we’ve seen in most DDR4 sticks – while Cors...
