1. Page mode read operation is faster than RAS read
2. RAS input remains active during column address strobe
3. The row and column addresses are strobed into the internal buffers using RAS and CAS inputs respectively

Assertion (A): Power drain of CMOS increases with operating frequency

Reason (R): All unused CMOS inputs should be tied either to a fixed voltage level (0 or V_DD) or to another input.
