    Burst Cycles
    Although NBT RAMs are designed to sustain 100% bus bandwidth by eliminating turnaround cycle when there is transition from
    read to write, multiple back-to-back reads or writes may also be performed. NBT SRAMs provide an on-chip burst address
    generator that can be utilized, if desired, to further simplify burst read or write implementations. The ADV control pin, when
    driven high, commands the SRAM to advance the internal address counter and use the counter generated address to read or write
    the SRAM. The starting address for the first cycle in a burst cycle series is loaded into the SRAM by driving the ADV pin low, into
    Load mode.
    Burst Order
    The burst address counter wraps around to its initial state after four addresses (the loaded address and three more) have been
    accessed. The burst sequence is determined by the state of the Linear Burst Order pin (LBO). When this pin is low, a linear burst
    sequence is selected. When the RAM is installed with the LBO pin tied high, Interleaved burst sequence is selected. See the tables
    below for details.

    Note:
    There is a pull-up device on the FT pin and a pull-down device on the ZZ pin, so this input pin can be unconnected and the chip will operate in
    the default states as specified in the above table.
    There are pull-up devices on the ZQ and SCD pins and a pull-down device on the ZZ pin, so those input pins can be unconnected and the chip
