a. MCQ (Single Correct Answer) GATE ECE 2017 Set 2 ... Each cell of a static Random Access Memory Contains. Each cell of a static Random Access memory contains a) 6 MOS transistor b) 4 MOS transistor, 2 capacitor c) 2 MOS transistor, 4 capacitor d) 1 MOS transistor and 1 capacitor Static RAM (SRAM, pronounced “es-ram”) is static because stored bits do not need to be refreshed. Static random access memories (SRAM) - one-bit memory cells use bistable latches for data storage and hence, unlike for dynamic RAM, there is no need to periodically refresh memory contents. Which of the following can access data even when the power supply is lost? Explanation: DRAM is highly denser and cheaper because it only uses a single capacitor for storing one bit. DRAM Memory Cell: Though SRAM is very fast, but it is expensive because of its every cell requires several transistors. Explanation: DRAM is said to be more volatile because it has a capacitor as its storage element in which the data disappears when the capacitor loses its charge so even when the device is powered the data can be lost. SRAM gives fast access to data, but it is physically relatively large.… Explanation: CMOS is complementary metal oxide semiconductor which is used by MAC and IBM PC as storage element because it contains configuration data of SRAM and is battery back-up to ensure that it is powered up when the computer is switched off. RAMs are divided in to two categories as Static RAM (SRAM) and Dynamic RAM (DRAM). When the wordline is asserted, both nMOS transistors turn on, and data values are transferred to or from the bitlines. This contains 20 Multiple Choice Questions for Computer Science Engineering (CSE) Test: SRAM And DRAM (mcq) to study with solutions a complete question bank. 4. For a NPN bipolar transistor, what is the main stream of current in the base region? Both A and R are true and R is correct explanation of A, B. 34) In a fixed channel assignment strategy. The number of columns of such a memory array is known as the bit width of each word. – A test that detects all SAFs guarantees that from each cell, a 0 and a 1 must be read. Unlike dynamic RAM, it does not need to be refreshed. students definitely take this Test: SRAM And DRAM exercise for a better result in the exam. ... Each cell of a Static Random Access Memory contains a. _____ 2147 RAM memory chip(s) is/are needed to configure an 8K × 8 memory A. Explanation: SRAM will retain data as long it is powered up and it does not need to be refreshed as DRAM. It has both the advantages of SRAM and DRAM. C. 3. Static RAM vs Dynamic RAM (SRAM vs DRAM) RAM (Random Access Memory) is the primary memory used in a computer. Explanation: Random Access Memory is the primary storage which can access data only when it is powered up. MCQ (Single Correct Answer) GATE ECE 1995. Explanation: DRAM is used in PCs and Embedded systems because of its low cost. This problem has been solved! 2. 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. The minimum number of MOS transistors required to make a dynamic RAM cell is. Which storage element is used by MAC and IBM PC? 10. Which type of storage element of SRAM is very fast in accessing data but consumes lots of power? It functions like a DRAM and has additional functions to access data for video hardware for creating the display. Figure 5.47 shows an SRAM bit cell. The data bit is stored on cross-coupled inverters like those described in Section 3.2.Each cell has two outputs, bitline and bitline ¯. Explanation: Pseudo RAM uses DRAM cells because of its higher memory density and it have refresh control which is an additional function of DRAM and is suitable for low power consumption. long questions & short questions for Computer Science Engineering (CSE) on EduRev as well by searching above. Dynamic RAM is the most commonly used RAM and is also considerably cheaper, but even static RAM has benefits. B-block who uses a 7 cell frequency reuse pattern with 3 sectors per cell • Use a Frequency Chart – available from FCC web site – Groups frequencies into 21 categories Cells 1-7 and sectors A-B in each cell Telcom 2720 20 Traffic Engineering • Given or N = T/K traffic channels per cell – what is GoS or how many users can be It contains ten thousand to more than a million logic gates with programmable interconnection. Fig: Static RAM cell Two inverters are cross connected to form a batch. 1. These computer memory questions and answers are very important for bank exams and other competitive exams. 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.
