WebP/E cycle: A solid-state-storage program-erase cycle is a sequence of events in which data is written to solid-state NAND flash memory cell (such as the type found in a so-called flash or thumb drive), then erased, and then rewritten. Program-erase (PE) cycles can serve as a criterion for quantifying the endurance of a flash storage device. WebFeb 1, 2016 · There’s another technology choice that can be made: floating gate vs. charge trap. With floating gate technology, you tunnel electrons onto an isolated gate from which they can’t escape (easily) unless erase conditions are set up (although a few leak off over time – hence the data retention spec). This is familiar from 2D flash. primary care network social workerWebAfter reviewing market trends for both NAND and solid state drives (SSDs), the book digs into the details of the flash memory cell itself, covering both floating gate and emerging … playboy western
