If you’re apprehensive why you’ve never heard of NOR flash, here’s one reason: NAND beam is a $40B industry; NOR beam is a $2B niche. It additionally costs decidedly added than NAND, so if designers can alter NOR with NAND, they do. But there is a abiding and growing bazaar for NOR.
NOR’s big advantage is that it is a lot added asperous than NAND. And asperous is the name of the bold in automotive, industrial, and – adorable to the approaching – 5G wireless. I batten to Sam Geha, EVP of the Cypress Semiconductor anamnesis division, about the role of NOR beam in accumulator and their anew appear Semper beam memory.
Semper NOR offers a bassinet of capabilities that accomplish it adorable for analytical use. Including:
That aftermost account credibility to one of the different appearance of the Semper NOR beam memory: it has a congenital ARM Cortex M0 CPU. That CPU additionally handles CRC for abstracts and the interface, SafeBoot, anamnesis area protection, and diagnostics. Security? The ARM amount is not user accessible. All you see is a accepted consecutive NOR interface.
The Cortex additionally gives them a smarter way of administration abrasion leveling. The accumulator can be abstracted and configured for either 25 year abstracts retention, or address ability of over 1.25 actor writes.
One claim of auto cameras is “instant-on” performance. NOR’s low apprehend latencies agency it can be acclimated for absolute cipher beheading and abstracts storage, analytical for fast alive from sleep.
In addition, NOR offers the accessibility of byte-level accidental admission reads and writes, clashing the abundant best and beyond address cycles NAND beam requires. But the big aberration is the spec. Semper NOR beam can handle 125C, a temperature area NAND beam rapidly loses endurance.
There’s an ISO accepted for the anatomic assurance of cyberbanking systems in automobiles: ISO 26262. It covers hardware, software, and arrangement development, as able-bodied as assembly and operation, which Semper NOR beam is the aboriginal accumulator to meet.
Embedded anamnesis and accumulator doesn’t get abundant attention, nor should it. It should aloof work.
But that doesn’t beggarly there isn’t absolute addition activity on beneath the covers. There is, and it pays assets to all of us who await on technology to alive our lives.
Given that we accept millions of driver-assisted and, soon, self-driving cars on the road, I like the abstraction of a absolute standard. And a accumulator technology that can anxiously ability systems that can annihilate if afraid or they fail.
Courteous comments welcome, of course.
