Note 2: Current flowing into an IC is positive, out is negative.
3: Icc1 (AV), Icc4 (AV) and Icc6 (AV) are dependent on cycle rate. Maximum current is measured at the fastest cycle rate.
4: Icc1 (AV) and Icc4 (AV) are dependent on output loading. Specified values are obtained with the output open.
5: Column address can be changed once or less while /RAS=VIL and /CAS=VOH
