PD411A-2 DESCR IPTION 4096 BIT DYNAMIC RAMS The ,uPD411A Famify consists of four 4096 words by 1 bit dynamic N-channel MOS RAMs.
They are designed for memory applications where very low cost and large bit storage are important design objectives.
The ,uPD411 A Family is designed using dynamic circuitry which reduces the standby power dissipation.
Reading information from the memory is non·destructive.
Refreshing is easily II accomplished by performing one read cycle on each of the 64 row addresses.
Each row address must be refreshed every two milliseconds.
The memory is refreshed whether Chip Select is a logic high or a logic low.
