272-bit Logical SEARCH
The logical 272-bit SEARCH operation is shown in
Figure 32. The entire table of 272-bit entries is
compared to a 272-bit word K (presented on the
DQ Bus in both Cycles A, B, C, and D of the com-
mand) using the GMR and the local mask bits. The
GMR is the 272-bit word specified by the two pairs
of GMRs selected by GMR Indexes in the com-
mand’s Cycles A and C. The 272-bit word K (pre-
sented on the DQ Bus in Cycles A, B, C, and D of
the command) is compared with each entry in the
table starting at location “0.”
The first matching entry’s location, address “L,” is
the winning address that is driven as part of the
SRAM address on the SADR[21:0] lines.
Note: The matching address is always going to be
location “0” in a four-entry page for a 272-bit
SEARCH (two LSBs of the matching index will be
“00”).
