Since the loading screen data itself needs to be read from the media, it actually can increase the overall loading time. For example, with a ZX Spectrum game, the screen data takes up 6 kilobytes , representing an increase in loading time of about 13% over the same game without a loading screen. [ 1 ]
Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device. Read-only memory is useful for storing software that is rarely changed during the life of the system, also known as firmware.
This way, only the offending program crashes, and other programs are not affected by the misbehavior (whether accidental or intentional). Use of protected memory greatly enhances both the reliability and security of a computer system. Without protected memory, it is possible that a bug in one program will alter the memory used by another program.
The device must be capable of 2.5 MB/s read speeds for 4 kB random reads spread uniformly across the entire device, and 1.75 MB/s write speeds for 512 kB random writes spread uniformly across the device. [10] The Microsoft Windows Client Performance group recommends a flash-memory-to-system-RAM ratio of between 1:1 and 2.5:1. [3]
[10] 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 ...
A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. [1] A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.
In a particular implementation, a special board is added to a computer, which controls the allocation of banks to memory space. The control board has its own memory chip. A computer can write data into this chip, but only the control board itself can read the chip, [note 1] hence it is dubbed "write only" memory. [7]: 200–202
Video random-access memory (VRAM) is dedicated computer memory used to store the pixels and other graphics data as a framebuffer to be rendered on a computer monitor. [1] It often uses a different technology than other computer memory, in order to be read quickly for display on a screen.
