Static random-access memory (static RAM or SRAM) is a type of random-access memory (RAM) that uses latching circuitry (flip-flop) to store each bit. SRAM is volatile memory; data is lost when power is removed. The static qualifier differentiates SRAM from dynamic random-access memory (DRAM):
The main advantage of static RAM (SRAM) is that it is much faster than dynamic RAM. Its disadvantage is its high price. SRAM does not need continuous electrical refreshes, but it still requires constant current to sustain the difference in voltage. Every single bit in a static RAM chip needs a cell of six transistors, whereas dynamic RAM ...
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.
The two main types of random-access memory (RAM) are static RAM (SRAM), which uses several transistors per memory cell, and dynamic RAM (DRAM), which uses a transistor and a MOS capacitor per cell. Non-volatile memory (such as EPROM, EEPROM and flash memory) uses floating-gate memory cells, which consist of a single floating-gate transistor per ...
Dynamic random-access memory (dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell, usually consisting of a tiny capacitor and a transistor, both typically based on metal–oxide–semiconductor (MOS) technology. While most DRAM memory cell designs use a capacitor and transistor ...
The two widely used forms of modern RAM are static RAM (SRAM) and dynamic RAM (DRAM). In SRAM, a bit of data is stored using the state of a six-transistor memory cell, typically using six MOSFETs. This form of RAM is more expensive to produce, but is generally faster and requires less dynamic power than DRAM.
However, the chip could not be used in the TOI since it required very expensive static RAM to operate fast enough. As the new decade began, the price of computer hardware was dropping and Tramiel saw an emerging market for low-price computers, that could be sold at retail stores to relative novices rather than professionals or people with an ...
Each MCS6530 comprises a mask programmable 1024 × 8 ROM, a 64 × 8 RAM, two eight-bit bi-directional ports, and a programmable interval timer. [3] The KIM-1 brochure said "1 K BYTE RAM" but it actually had 1152 bytes. The memory was composed of eight 6102 static RAMs (1024 × 1 bits) and the two 64-byte RAMs of the MCS6530s.
