Memory question

irishdude11 · 2011-05-11 11:24:45

Dont know where else to ask this question. How many address lines and data lines would are in a 4096 X 16 memory chip? Is it simply 4096 address lines and 16 data lines or am I overlooking something?

If it's a parallel bus chip (and with the exception of some I2C chips used mostly in embedded systems, it will be), or some 16-to-8-bit-multiplexing logic like the old 68008 used to have, it'll most likely be 16 data lines and 12 address lines (4096=2^12). Of course, if it's in a system with more than 12 address lines, there might be more than 12 pins, but the remainder would be unconnected internally (and it's fairly rare to do that anyway).
