type of MRS (Regular/Extended MRS). EMRS cycle can be implemented the extended function (DLL
enable/Disable mode)
The initial value of the Mode Register (including EMRS) after power up is undefined; therefore the
Mode Register Set command must be issued before power operation.
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, 4, and 8 words.

2. Addressing Mode Select (A3)
The Addressing Mode can be one of two modes; 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
addressing Mode support burst length 2, 4, and 8 words.
