It handles reading and writing, voltage regulation, and different duties together with error correction and unhealthy sector management. The controller may incorporate put on leveling strategies to increase the life of the card by monitoring and distributing knowledge so sure areas of the card aren't overused. The controller immediately affects the transfer pace capabilities of a memory card. Who makes flash memory? While there are a lot of manufacturers of memory cards, very few manufacture the memory chips used inside the playing cards. Of the most important memory card manufacturers, only Samsung, SanDisk, Toshiba and Lexar are concerned in memory chip manufacturing. Samsung is the main producer of NAND memory worldwide and opened a brand new $7 billion facility in Xi'an, China to provide NAND flash memory in Could, 2014. Toshiba and SanDisk co-personal a memory production facility in Yokkaichi, Japan.

Micron, proprietor of Lexar, produces memory chips in a joint enterprise with Intel at a facility in Lehi, Utah and assembles their playing cards in Asia. Other NAND memory chip manufacturers include TSMC in Taiwan and SK Hynix of South Korea. Flash controllers for SD and cognitive enhancement tool CF playing cards are manufactured by Samsung, Micron, Sandisk, Toshiba and Sony in addition to a number of independent manufacturers including Alcor Micro, JMicron, Phison, SiliconMotion (SMI) and Hyperstone. Flash memory card brands in a roundabout way concerned in manufacturing could use one or more of the above suppliers. Kingston is thought for utilizing Toshiba/SanDisk chips and controllers, Transcend has used Samsung chips and SMI-produced controllers, Delkin makes use of Toshiba, Samsung and Micron chips and customized controllers from numerous manufacrurers including Hyperstone. The controller is a vital part of a memory card
