Characteristics Of Computer Memory

A device used to save data and instructions which is computer memory. In binary form is the content of memory. In order to carry out all kinds of operations, memory offers input to the processors. Thus, the processors save the results into memory (World of Computing, 2013). The characteristic of computer memory which are electrical characteristics, the manufacturing technology of the device depend on the voltage and current requirements. It is not main concern of the voltage due to most of the semiconductor memory device manipulate at TTL voltage levels. In addition, speed also is the characteristic of computer memory. There is a limit time to delay between the usability of stabilize and accurate of the data on the data lines because of the

ROM saves data everlasting written on it. It was usually called non- volatile memory because of it was keeps the data when the power is turned off (All about computer parts, 2010). Thus, this is an important characteristic of Read-Only Memory. To save computer startup instructions which is ROM. This instruction is preprogram by the manufacturer so it means you unable to change or rewrite on ROM. Nevertheless, they can used a new version supplied to update BIOS by manufacturer in recently systems. EPROM and PROM which are the other types of non-volatile memory. RPOM is Programmable read only memory, it is a type of ROM on which instruction is programmed. It was suitable for video games to save instructions and settings. Otherwise, EPROM is Erasable programmable read-only memory, it is a type of ROM which able to erasure and reprogrammable (All about computer parts,

This is the main memory of a computer, it can temporarily to saves the copy of documents and files loaded from hard disk that demands by a processors. After finish to modify or change the loaded file, it must be keep into hard disk before the power is turned off. If the power turn off without saving, you won’t get back the change make on original file. They lose the information when the power is turned off referred as these computer memory types (All about computer parts, 2010).There are many varieties of RAM, which are Fast Page DRAM, it was expanded data output or EDO RAM is the other type of RAM because it is faster than other earlier memory types. DDR2 and DDR3 SDRAM, they founded that these are the computer memory types in recent system. At present, DDR3 is the newest and fastest smashing the maximum speed of 1066MHz realized by DDR2 RAM but its power consumption is lower than DDR2. Hence, RAM is low-priced but there are different volume and size. Relative to a processor, the speed of computer memory slowly as usual, which hangs the performance of a processor in order to solve this problem, the new type of memory is open up which is SRAM (All about computer parts,
