# Detail the MK4096 Pinout and Packaging
The MK4096 packed power, ground, six multiplexed address pins, data in, data out, chip select, and the RAS and CAS control pins into a sixteen-pin dual in-line package.
That pinout fit an industry-standard package body that board designers already had sockets and footprints for, which lowered the adoption barrier compared to a part that demanded new board layouts.
The specific arrangement Mostek chose for these sixteen pins became, in practice, the reference pinout that other 4K DRAM makers aligned to so their parts could be dropped into the same sockets.
