Hard Disk Drive (HDD) A hard disk drive is used to store vast amount of data. A Flip-flop consists of a few transistors and therefore the cost of a static RAM is higher, though it is compact. In the absence of a capacitor, there is no need to cater for the refresh cycle and this makes the static RAM considerably faster than a dynamic RAM.
#MEMORIA ROM SERIES#
Another type of RAM is the static RAM, where the integrated chip consists of a series of Flip-flops instead of a combination of a transistor and a capacitor. The combined working of all the devices makes it slow in working. Since the data can be accessed and written dynamically, these are called dynamic random access memory. In addition to the charging circuitry, it consists of a control circuit which is used to read and write data. Due to the nature of a capacitor (it discharges at a very fast rate), it is required to charge them periodically. If the capacitor is charged at 50 % or more, it reflects a binary one. It is a integrated chip consisting of rows and columns of a pair of transistor and a capacitor forming a grid. RAM, Random Access Memory This type of memory is essential for the working of a computer.
The required portion of the memory can be erased or written on in a selective basis. 3.EEPROM, Electrical Erasable Programmable Read only Memory This kind of ROM is popular in memory sticks. This is a tedious process and excess exposure may lead to destruction of the ROM. Ultraviolet light is used to erase the information. 2.EPROM Erasable Programmable Read only Memory This is an improvement on PROM. When an electric charge is passed through it, it ruptures the fuse and becomes a zero. In the initial stage the complete grid represents a binary one. PROM contains a fuse at the junction of each row and column of the grid.
