Solid-state modules that fit in a dual inline memory module (DIMM) or small outline dual inline memory module using a standard HDD interface, such as the Serial Advanced Technology Attachment (SATA).Īn additional subcategory is a hybrid hard drive that combines a conventional HDD with a NAND flash module.Solid-state cards that reside on a printed circuit board and use a standard card form factor, such as Peripheral Component Interconnect Express ( PCIe).SSDs have architecture similar to that of an integrated circuit. SSDs that fit into the same slots used by traditional electromechanical hard disk drives (HDDs).There are three SSD form factors that have been identified by the Solid State Storage Initiative: Also known as solid-state devices, they are widely used in both consumer electronics and enterprise data storage systems. Flash memory form factorsįlash-based media is based on a silicon substrate.

NAND flash is more suitable for data storage in consumer devices and enterprise server and storage systems due to its lower cost per bit to store data, greater density and higher programming and erase (P/E) speeds.ĭevices, such as camera phones, may use both NOR and NAND flash, in addition to other memory technologies, to facilitate code execution and data storage. NOR flash is more expensive to produce than NAND flash and tends to be used primarily in consumer and embedded devices for boot purposes and read-only applications for code storage. NAND flash consumes less power than NOR flash for write-intensive applications. For instance, a page might be 4 kilobytes (KB), while a block might be 128 KB to 256 KB or megabytes in size.
NAND flash programs data in pages, which are larger than bytes, but smaller than blocks. NOR flash programs data at the byte level. NOR flash is fast on data reads, but it is typically slower than NAND on erases and writes. NAND flash process geometries were developed in response to planar NAND reaching its practical scaling limit. NAND is better suited to serial rather than random data access. A NAND flash cell is more compact and has fewer bit lines, stringing together floating gate transistors to increase storage density. NOR flash uses no shared components and can connect individual memory cells in parallel, enabling random access to data. NOR and NAND flash memory differ in architecture and design characteristics. There are two types of flash memory: NOR and NAND. This characteristic enables flash memory to provide persistent storage. Masuoka's colleague, Shoji Ariizumi, reportedly coined the term flash because the process of erasing all the data from a semiconductor chip reminded him of the flash of a camera.Įlectrons are trapped in the floating gate whether or not a device containing the flash memory cell is receiving power as a result of electrical isolation created by the oxide layer.
Fujio Masuoka is credited with the invention of flash memory when he worked for Toshiba in the 1980s. NOR flash memory is often used to hold control code, such as the basic input/output system (BIOS), in a PC.įlash memory is also used for in-memory computing to help speed performance and scalability of systems that manage and analyze large sets of data. For instance, NAND flash-based solid-state drives are often used to accelerate the performance of I/O-intensive applications.

Flash memory retains data for an extended period of time, regardless of whether a flash-equipped device is powered on or off.įlash memory is used in enterprise data center server, storage and networking technology, as well as in a wide range of consumer devices, including USB flash drives - also known as memory sticks - SD cards, mobile phones, digital cameras, tablet computers and PC cards in notebook computers and embedded controllers. Flash memory is widely used for storage and data transfer in consumer devices, enterprise systems and industrial applications. Flash memory, also known as flash storage, is a type of nonvolatile memory that erases data in units called blocks and rewrites data at the byte level.
