Memory in TK-Gate
With all memory, make sure that the signals going into the device are stable
so the device has a chance to change state. (Propagation delay and why it is
important)
RAM
- Inputs to memory
- An address line
- A data line
- A Write Enable (not) line, write when this is low
- A Chip Select (not) line, chip is active when this is low
- An Output Enable (not) line, retrieve the value from memory
when this is low.
- Memory appears to be word addressable.
- Word size appears to be detemined by the width of the D line.
- Memory size appears to be determined by the size of the A line.
