CFG = 0101010101010101, HLAT = 001, TLSZ = 10, LRAM = 1, LDEV = 1.
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.
The following is the sequence of operation for a single 144-bit Search command (also refer to “Command and Command
Parameters,” on page 22).
Document #: 38-02040 Rev. *F
• Cycle A: The host ASIC drives the CMDV high and applies Search command code (10) on CMD[1:0] signals. {CMD[10],
CMD[5:3]} signals must be driven with the index to the GMR pair for use in this Search operation. CMD[8:6] signals must be
driven with the bits that will be driven on SADR[23:21] by this device if it has a hit. DQ[71:0] must be driven with the 72-bit data
([143:72]) in order to be compared against all even locations. The CMD[2] signal must be driven to logic 0.
