SRAM offers a simple data access model and does not require a refresh circuit. Performance and reliability are good and power consumption is low when idle. [11] Since SRAM requires more transistors per bit to implement, it is less dense and more expensive than DRAM and also has a higher power consumption during read or write access. The power ...
Pinout of the 6264 SRAM IC. The 6264 is a JEDEC-standard static RAM integrated circuit. It has a capacity of 64 Kbit (8 KB). It is produced by a wide variety of different vendors, including Hitachi, Hynix, and Cypress Semiconductor. It is available in a variety of different configurations, such as DIP, SPDIP, and SOIC.
Commercial use of SRAM began in 1965, when IBM introduced the SP95 memory chip for the System/360 Model 95. [ 11 ] Dynamic random-access memory (DRAM) allowed replacement of a 4 or 6-transistor latch circuit by a single transistor for each memory bit, greatly increasing memory density at the cost of volatility.
SRAM became an alternative to magnetic-core memory, but required six MOS transistors for each bit of data. [21] Commercial use of SRAM began in 1965, when IBM introduced their SP95 SRAM chip for the System/360 Model 95. [9] Toshiba introduced bipolar DRAM memory cells for its Toscal BC-1411 electronic calculator in 1965.
In electronics, a driver is a circuit or component used to control another circuit or component, such as a high-power transistor, liquid crystal display (LCD), stepper motors, SRAM memory, [1]: 30 and numerous others.
Pseudostatic RAM (PSRAM or PSDRAM) is dynamic RAM with built-in refresh and address-control circuitry to make it behave similarly to static RAM (SRAM). It combines the high density of DRAM with the ease of use of true SRAM. PSRAM is used in the Apple iPhone and other embedded systems such as XFlar Platform. [65]
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 ...
These circuits require a timing generator or clock for their operation. [3] Computer memory used in most contemporary computer systems is built mainly out of DRAM cells; since the layout is much smaller than SRAM, it can be more densely packed yielding cheaper memory with greater capacity. Since the DRAM memory cell stores its value as the ...
