Each cell is assigned a predetermined set of frequencies b. DRAM has storage element as a capacitor whose charge loses gradually thereby losing data. B. Static RAM vs Dynamic RAM (SRAM vs DRAM) RAM (Random Access Memory) is the primary memory used in a computer. Explanation: The low power consumption makes SRAM easily convertible to non-volatile memory, by adding a small battery it can retain its data even when the main power is lost. This problem has been solved! Explanation: Random Access Memory is the primary storage which can access data only when it is powered up. Explanation: Four to six transistors are used to store a single bit of data and form a flip-flop logic gate and thus SRAM is faster in accessing data. It displays several cells that together form a mesh that includes rows and columns, each cell containing alphanumeric text, numeric values, or formulas. Static RAM uses a completely different technology. The full form of FPGA is “Field Programmable Gate Array”. Explanation: DRAM uses a small capacitor whose voltage represents a binary zero which is used a storage element in DRAM in which a single transistor cell is used to store each bit of data. Gets blocked c. Is kept on waiting d. All of the above. This form of semiconductor memory gains its name from the fact that data is held in there in a static fashion, and does not need to be dynamically updated as in the case of DRAM memory.
