The following is the sequence of operation for a single 272-bit Search command (also refer to Subsection 12.2, “Commands and
Command Parameters” on page 19).
• Cycle A: The host ASIC drives CMDV high and applies Search command code (10) on CMD[1:0] signals. CMD[5:3] signals
must be driven with the index to the GMR pair used for bits[271:136] of the data being searched. DQ[67:0] must be driven with
the 68-bit data ([271:204]) to be compared to all locations 0 in the four 68-bits-word page. The CMD[2] signal must be driven
to logic 1. Note. CMD[2] = 1 signals that the search is a x272-bit Search. CMD[8:6] is ignored in this cycle.
• Cycle B: The host ASIC continues to drive CMDV high and applies Search command (10) on CMD[1:0]. The DQ[67:0] is
driven with the 68-bit data ([203:136]) to be compared to all locations 1 in the four 68-bits-word page.
• Cycle C: The host ASIC drives CMDV high and applies Search command code (10) on CMD[1:0] signals. CMD[5:3] signals
must be driven with the index to the GMR pair used for the bits [135:0] of the data being searched. CMD[8:6] signals must be
driven with the bits that will be driven by this device on SADR[21:19] if it has a hit. DQ[67:0] must be driven with the 68-bit data
([135:68]) to be compared to all locations 2 in the four 68-bits-word page. The CMD[2] signal must be driven to logic 0.

Note: |(BHI[2:0]) stands for the boolean ‘OR’ of the entire bus BHI[2:0]
Note: |(LHI[6:0]) stands for the boolean ‘OR’ for the entire bus LHI[6:0]
Note: Each bit in BHO[2:0] is the same logical signal.
Note: Each bit in LHO[1:0] is the same logical signal.
