IC 4116 is a DRAM of 16 KB storage memory. It requires three supply voltages (+5V, -5V, and +12V) to operate the IC unit.
DRAM is fabricated by using IC __________
7489
2776
2114
4116
DRAM is Dynamic RAM which takes more access time compared to SRAM and is thus, slower in operation comparatively. Although, in general it offers high speed and is used in most computers nowadays. DRAM is fabricated by using IC 4116.
By which technology, semiconductor memories are constructed?
VLSI
PLD
Both LSI and VLSI
LSI
Generally, semiconductor memories are constructed using Large Scale Integration (LSI) or Very Large Scale Integration (VLSI) because these are made up of NMOS, CMOS, BJT, etc.
Magnetic core is the digital memory in which data is stored magnetically in individual cores operated by __________
Up and down select wires
Up and Serial select wires
Row and column select wires
Serial and parallel select wires
Magnetic core is the digital memory in which data is stored magnetically in individual cores operated by row and column select wires, with data obtained from sense wire.
Magnetic drum is a storage medium using __________
The surface of a rotating magnetic drum
The surface of a jumping magnetic drum
The surface of a stopped magnetic drum
The surface of a moving magnetic drum
Magnetic drum is a storage medium using the surface of a rotating magnetic drum which have tendency to hold the data.
Magnetic recording is the process of __________
Both storing data symmetrically and sequentially
Storing data sequentially
Storing data magnetically
Storing data symmetrically
Based on material used for construction, memory devices are classifieds into two categories, viz., Magnetic and Semiconductor memory. Magnetic recording is the process of storing data magnetically. Hard disk, floppy disk, magnetic tape are examples of the magnetic recording process.

The example of non-volatile memory device is __________
Magnetic Core Memory
Both Magnetic Core Memory and Read Only Memory
Read Only Memory
Random Access Memory
Non-volatile means ‘not volatile’ and non-volatile memory refers to the memory which retains the data even if there is a break in the power supply. The examples of non-volatile memory devices are Magnetic Core Memory & ROM because both have capability to retain the data.
Non-volatile memory refers to __________
The memory whose loosed data is achieved again when power to the memory circuit is applied
The memory whose loosed data is retained again when power to the memory circuit is removed/applied
The memory which looses data when power to the memory circuit is applied
The memory which looses data when power to the memory circuit is removed
Volatile means ‘liable to change rapidly’ and volatile memory refers to the memory which looses data rapidly when power to the memory circuit is removed. Thus, it looks after it’s data as long as it is powered. Non-volatile means ‘not volatile’ and non-volatile memory refers to the memory which retains the data even if there is a break in the power supply.
Volatile memory refers to __________
The memory which looses data when power to the memory circuit is removed
The memory whose loosed data is achieved again when power to the memory circuit is removed

In dynamic memory, CCD stands for __________
Charge Coupled Devices
Change Coupled Devices
Charged Compact Disk
Charged Count Devices
In dynamic memory, CCD stands for Charge Coupled Devices.
The example of dynamic memory is __________
CCD
Floppy-Disk
Semiconductor dynamic RAM
Both CCD and semiconductor dynamic RAM
The examples of dynamic memories are CCD and semiconductor dynamic RAM because of the contents of both the memories changes with time.
Static memory holds data as long as __________
Capacitor is fully charged
High Conductivity
DC power is applied
AC power is applied
In any semiconductor equipment, AC power can’t be supplied directly. So, static memory holds the data as long as DC power is applied.

4
Only one bit transistor is needed to store 1-bit of information.
Dynamic memory cells use _______________ as the storage device.
The impedance of a transistor
The reactance of a transistor
The capacitance of a transistor
The inductance of a transistor
Capacitance of a transistor prevents from loss of information in a dynamic memory cell.
