  2. Static random-access memory - Wikipedia

    en.wikipedia.org/wiki/Static_random-access_memory

    SRAM will hold its data permanently in the presence of power, while data in DRAM decays in seconds and thus must be periodically refreshed. SRAM is faster than DRAM but it is more expensive in terms of silicon area and cost. Typically, SRAM is used for the cache and internal registers of a CPU while DRAM is used for a computer's main memory.

  4. Memory timings - Wikipedia

    en.wikipedia.org/wiki/Memory_timings

    Because system performance depends on how fast memory can be used, this timing directly affects the performance of the system. The timing of modern synchronous dynamic random-access memory (SDRAM) is commonly indicated using four parameters: CL , T RCD , T RP , and T RAS in units of clock cycles ; they are commonly written as four numbers ...

    Cover of the comic book "THE SHMOO" The plot takes its name from the Shmoo, a fictional species created by Al Capp in the cartoon Li'l Abner.These small, blob-like creatures have shapes similar to the "working" volumes that would be enclosed by shmoo plots drawn against three independent variables (such as voltage, temperature, and response speed).

    English: Circuit diagram of an SRAM cell, built with six MOSFETs. The bulk connection of all transistors is to ground, but is not shown from simplicity. The bulk connection of all transistors is to ground, but is not shown from simplicity.

  8. Digital timing diagram - Wikipedia

    en.wikipedia.org/wiki/Digital_timing_diagram

    A timing diagram can contain many rows, usually one of them being the clock. It is a tool commonly used in digital electronics, hardware debugging, and digital communications. Besides providing an overall description of the timing relationships, the digital timing diagram can help find and diagnose digital logic hazards .

  9. Memory refresh - Wikipedia

    en.wikipedia.org/wiki/Memory_refresh

    Static random-access memory (SRAM) is electronic memory that does not require refreshing. [2] An SRAM memory cell requires four to six transistors, compared to a single transistor and a capacitor for DRAM; therefore, SRAM circuits require more area on a chip. As a result, data density is much lower in SRAM chips than in DRAM, and gives SRAM a ...
