With each successive generation of flash storage, prices go down and storage capacities increase. This is due to the smaller build processes producing more NAND chips and the smaller chips being able to be used in higher densities inside devices.

Samsung has announced that it is now introduction with a new line of 20nm NAND flash chips that use MLC tech. The new chips are being made in 32Gb capacity and will be used in smartphones, memory cards, and other devices.

A report released from Prudential Equity Group recently indicated that Apple may scrap plans for the next generation hard drive based iPod in favor of using NAND flash memory instead. The change according to the report would result in smaller players and improvements in battery life and durability.

NAND flash memory is a very common source of memory for small thumb drives and memory cards, and is a type of non-volatile memory. Non-volatile memory means that it does not need a continuous power source to retain its data, and NAND flash memory is a durable design that works well for long-term use.

Using the flash memory for iPods would also mean less required power since there are no moving parts, and with the continuing improvements in flash technology the devices can be built smaller without compromising …
