Many game consoles use interchangeable ROM cartridges, allowing for one system to play multiple games. Shown here is the inside of a Pokémon Silver Game Boy cartridge. The ROM is the IC on the right labeled "MX23C1603-12A". Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices.
Prior to the development of integrated read-only memory (ROM) circuits, permanent (or read-only) random-access memory was often constructed using diode matrices driven by address decoders, or specially wound core rope memory planes. [citation needed] Semiconductor memory appeared in the 1960s with bipolar memory, which used bipolar transistors ...
Page mode DRAM was in turn later improved with a small modification which further reduced latency. DRAMs with this improvement are called fast page mode DRAMs (FPM DRAMs). In page mode DRAM, the chip does not capture the column address until CAS is asserted, so column access time (until data out was valid) begins when CAS is asserted.
Non-volatile random-access memory (NVRAM) is random-access memory that retains data without applied power. This is in contrast to dynamic random-access memory (DRAM) and static random-access memory (SRAM), which both maintain data only for as long as power is applied, or forms of sequential-access memory such as magnetic tape, which cannot be randomly accessed but which retains data ...
To emphasize the advantages of the DDR technique, this type of RAM was marketed at speeds twice the actual clock rate, i.e. the 400 MHz Rambus standard was named PC-800. This was significantly faster than the previous standard, PC-133 SDRAM , which operated at 133 MHz and delivered 1066 MB/s of bandwidth over a 64-bit bus using a 168-pin DIMM ...
The time to read the first bit of memory from a DRAM without an active row is T RCD + CL. Row Precharge Time T RP: The minimum number of clock cycles required between issuing the precharge command and opening the next row. The time to read the first bit of memory from a DRAM with the wrong row open is T RP + T RCD + CL. Row Active Time T RAS
Tiny Core Linux is an example of Linux distribution that run from RAM. This is a list of Linux distributions that can be run entirely from a computer's RAM, meaning that once the OS has been loaded to the RAM, the media it was loaded from can be completely removed, and the distribution will run the PC through the RAM only.
