272-bit Search on Tables Configured as 272 Using a Single CYNSE70064A Device
The following is the sequence of operation for a single 136-bit Search command (also refer to Subsection 10.2, “Commands and
Command Parameters” on page 18).
Cycle A
: The host ASIC drives the 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 ×272-bit Search. CMD[8:3] in this cycle is ignored.
