A '''flash memory controller''' (or '''flash controller''') manages data stored on [[flash memory]] (usually [[NAND flash]]) and communicates with a [[computer]] or [[electronic device]]. Flash memory controllers can be designed for operating in low [[duty-cycle]] environments like [[memory card]]s, or other similar [[Data storage device|media]] for use in [[digital camera]]s, [[Personal digital assistant|PDA]]s, [[mobile phone]]s, etc. [[USB flash drive]]s use flash memory controllers designed to communicate with [[personal computer]]s through the [[USB port]] at a low duty-cycle. Flash controllers can also be designed for higher duty-cycle environments like [[solid-state drive]]s (SSD) used as data storage for [[laptop]] computer systems clear up to [[mission-critical]] enterprise [[storage array]]s.<ref name="kingston">{{cite web|title=Flash Memory Guide|url=http://media.kingston.com/pdfs/FlashMemGuide.pdf|publisher=kingston.com|access-date=7 March 2013}}</ref>
