A flash memory is an essential component in an electronics device to store code and data. Every designer expects a perfect non-volatile memory to meet their requirements. The electronics devices are growing very fast, so we can find a variety of flash memories. However, the flash memories vary in timing, bus width, protocol, rewrite lifecycle, multi-level capability and native support of microprocessor. So the designers have to study the available products to select a proper device for their applications according to the storage purpose, interface and timing.

A SSD (solid state drive) is a data storage device and uses solid state memory to store persistent data.
Intel launched its new family of solid state drives claiming a significant performance advantage over its competitors. Solid state drives are small, lightweight and durable but they come with a high price tag and are typically slow. However, researchers in Korea have found a way of making these storage devices faster. The technique involves mixing two types of memory to increase the overall speed without also jacking up the price.
