Flash memory has been widely used in the storage system, mainly due to its superiority such as smaller size, lower power consumption, faster read performance and no mechanical delay. Though the traditional multi-dimensional applications with spatial data management, such as GIS, CAD/CAM, data mining, could directly run over flash memory under the support of FTL (Flash Translation Layer), the performance...
Traditional magnet disk is not likely to improve read and write speed, due to its physical characteristics. Solid State Drive (SSD) has much higher random write and read speed than a magnet disk, and the absence of moving parts also makes SSD consume less energy and noiseless. However, traditional database can't exert the high performance of SSD because of the different characteristics between magnetic...
Flash memory is being rapidly deployed as data storage for mobile devices. With its capacity increasing and price dropping, flash memory will finally take the place of magnetic disk. It is possible for us to consider running a database system on the flash computing platforms. Therefore, this requires an efficient index structure to locate a particular item quickly from a huge amount of database records...
Flash memory, especially NAND flash memory, is being rapidly deployed as data storage for mobile devices such as mobile phones, digital cameras and PDA's. With its capacity increasing and price dropping, Flash memory has been installed in many portable computers instead of magnetic disk for its light weight, small size, physical stability and low power consumption. We may expect that Flash memory...
Flash memory is getting more popularity for its non-volatility, shock resistance, no mechanical delay and random access. Increasing size of flash memory as well as decrease in price has strengthened the possibility of replacing hard disk in near future. In this survey paper we discussed about the technological constraints of flash memory and how these problems has been solved so far. This survey paper...
