Extended Data Output (EDO) Page Mode
The EDO page mode is a kind of page mode with enhanced features. The two major features
of the EDO page mode are as follows.
1. Data output time is extended.
instead of the rising edge. For this reason, valid data output time in the EDO page mode is
extended compared with the fast page mode (=data extend function). In the fast page mode,
the data output time becomes shorter as the CAS cycle time becomes shorter. Therefore, in
the EDO page mode, the timing margin in read cycle is larger than of the fast page mode
even if the CAS cycle time becomes shorter.
2. The CAS cycle time in the EDO page mode is shorter than that in the fast page mode.
shorter than in the fast page mode if the timing margin is the same.
mode is 25ns while that in the fast page mode is 40ns.
repeatedly during one RAS cycle. The EDO page mode allows both read and write
operations during one cycle, but the performance is equivalent to that of the fast page mode
in that case.
In the EDO page mode, the output data is held to the next CAS cycle‘s falling edge,
In the EDO page mode, due to the data extend function, the CAS cycle time can be

In the EDO page mode, read (data out) and write (data in) cycles can be executed
