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.
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.

In the case of a digital circuit, this will then be further mapped into delay information from which the circuit performance can be estimated, usually by static timing analysis. This, and other final tests such as design rule checking and power analysis collectively called signoff are intended to ensure that the device will function correctly ...
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 .
VCM inserts an SRAM cache of 16 "channel" buffers, each 1/4 row "segment" in size, between DRAM banks' sense amplifier rows and the data I/O pins. "Prefetch" and "restore" commands, unique to VCSDRAM, copy data between the DRAM's sense amplifier row and the channel buffers, while the equivalent of SDRAM's read and write commands specify a ...

nvSRAM is one of the advanced NVRAM technologies that are fast replacing the battery-backed static random-access memory (BBSRAM), especially for applications that need battery-free solutions and long-term retention at SRAM speeds. nvSRAMs are used in a wide range of situations: networking, aerospace, and medical, among many others [3] where the ...
