Paper Title: SLC NAND gains momentum in Autonomous Driving camera applications

Paper Abstract: Autonomous driving systems now will perform real time fusion of information collected from some or all of following sensors: Cameras, Radars, Lidars, and Ultrasonic sensors. The initial ADAS systems introduced ten years ago offered camera with only limited functionality, but front cameras for Autonomous driving now offer tremendous image processing capability, with explosion in memory requirement for both Flash and DRAM. NOR had been the preferred Flash memory due to robust requirements in ADAS applications. But while Flash density usage was only up to 256Mb few years ago, Flash requirement has exploded now to 1Gb~2Gb densities due to increased code and data requirement in front camera applications. Unfortunately NOR Flash scaling hit big speed bump at 65nm few years ago and now stalling at 4X-nm, which makes NOR expensive solution above 256Mb, so System Architects must consider alternate solutions. SPI SLC NAND offered at technology node such as 4X-nm can offer 10,000 P/E cycle with 15 years data retention at 70C, which is comparable to NOR Flash. NAND Flash also offers much faster Program and Erase times which is great value in emerging Software update over the air applications.

He is Technical Executive at Winbond Electronics and currently managing Technical Marketing for Flash products in Europe and Israel. He was manager of Winbond’s first Serial NAND product design team prior to Marketing role, has been co-inventor on two key Serial NAND issued patents, and presented paper on Winbond’s unique Serial NAND Arch in 2013 Flash Memory Summit. He managed SPI NOR development activity at Atmel during 1995~2007, and developed Industry’s first commercially successful SPI NOR product line (called DataFlash) while at Atmel. He designed Industry’s first EEPROM (EEPROM is predecessor to Flash memories) with on-chip charge-pump while at SEEQ and presented pioneering paper in 1982 ISSCC (IEEE) conference.
