Notes: 2. Input and output currents are excluded. When a CMOS input is floating, excess current flows
from the power supply through to the input circuit. To avoid this, VIH and VIL must be held to
V_CC and GND levels, respectively.
3. Indicates the current when the memory access is stopped and the still image of a zig-zag
pattern is displayed in its place.
