SDRAM/SGRAM Components D.C. Operating Requirements
NOTES:
1. Input leakage currents include hi-Z output leakage for all bi-directional buffers with tri-state outputs.
2. This is a recommendation, not an absolute requirement. The actual value should be provided with the
component data sheet.
9.3
SDRAM/SGRAM Components Absolute Maximum A.C.
Operating Requirements
NOTE: The overshoot and undershoot voltage duration is
≤
5ns with no input clamp diodes.
