Solution

The correct option is B 1

The minimum number of MOS transistors required to male a dynamic RAM cell is 1

The metal-oxide-semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of field-effect transistor (FET), most commonly fabricated by the controlled oxidation of silicon. It has an insulated gate, whose voltage determines the conductivity of the device.

This refresh requirement gives rise to the term dynamic - static memories do not have a need to be refreshed. The advantage of a DRAM is the simplicity of the cell - it only requires a single transistor compared to around six in a typical static RAM, SRAM memory cell.

There are two different types of RAM; DRAM (Dynamic Random Access Memory) and SRAM (Static Random Access Memory). The two types differ in the technology they use to hold data, with DRAM being the more common type. In terms of speed, SRAM is faster.
