To address this, as well as space limitations, some developers have produced special versions of operating systems such as Linux in Live USB  or commonplace applications such as Mozilla Firefox designed to run from flash drives. Semiconductor corporations have worked to reduce the cost of the components in a flash drive by integrating various flash drive functions in a single chip, thereby reducing the part-count and overall package-cost.

Flash drives use little power, have no fragile moving parts, and for most capacities are small and light. The development of high-speed serial data interfaces such as USB made semiconductor memory systems with serially accessed storage viable, and the simultaneous development of small, high-speed, low-power microprocessor systems allowed this to be incorporated into extremely compact systems. Since first appearing on the market in late , as with virtually all other computer memory devices, storage capacities have risen while prices have dropped. Archived from the original on 8 July For high-reliability data storage, however, it is not advisable to use flash memory that would have to go through a large number of programming cycles. A number of blocks on the flash chip may be set aside for storing mapping tables to deal with bad blocks, or the system may simply check each block at power-up to create a bad block map in RAM.
