Memory (RAM) refers to a read/write memory device that can read
data from or write data to any of its memory addresses,
regardless of what memory address was last accessed for reading
or writing. RAM comes in two data in cells that depend on
capacitors, which need to be 'refreshed' continuously since they
are not able to retain data indefinitely even if the device is
continuously powered up. SRAMs, on the other hand, store data in
flip-flops, which retain data without refreshing as long as the
SRAM is powered up. memory per unit chip area compared to SRAMs,
mainly because of the much simpler structure of its storage
element. Whereas an SRAM memory cell consists of 4 to 6
transistors, a DRAM memory cell consists of only a single
transistor that is paired with a capacitor. The presence or
absence of charge in the capacitor determines whether the cell
contains a '1' or a '0'. This single-transistor configuration is
commonly referred to as a 1-T memory A typical DRAM IC has
address lines, data lines, and control
