Functional Description (Continued)
Regular Mode Register/Extended Mode Register change bits (BA0, BA1)
These bits are used to choose either Regular MRS or Extended MRS
Regular Mode Register Fields
(R-1) Burst Length field (A2 to A0)
This field specifies the data length for column access using the A2 to A0 pins and sets the Burst Length to be 2 or 4
words.
(R-2) Burst Type field (A3)
This Burst Type can be chosen Interleave mode or Sequential mode. When the A3 bit is " 0", Sequential mode is
selected. When the A3 bit is "1", Interleave mode is selected. Both burst types support burst length of 2 and 4 words.
Addressing sequence of Sequential mode (A3)
A column access is started from the inputted lower address and is performed by incrementing the lower address input to
the device. The address is varied by the Burst Length as the following.
