Figure 86. Multi-Width Configurations Example
LRAM AND LDEV DESCRIPTION
When search engines are cascaded using multiple
M7020Rs, the SADR, CE_L, and WE_L (3-state
signals) are all tied together. In order to eliminate
external pull-up and pull-downs, one device in a
bank is designated as the default driver. For non-
SEARCH or non-LEARN cycles (see LEARN
COMMAND in the section below) or search cycles
with a global miss, the SADR, CE_L, and WE_L
signals are driven by the device with the LRAM Bit
set.
Note:
It is important that only one device in a bank
of search engines that are cascaded have this bit
set. Failure to do so will cause contention on
SADR, CE_L, WE_L, and can potentially cause
damage to the device(s).
Similarly, when search engines using multiple
M7020Rs are cascaded, SSF and SSV (also 3-
state signals) are tied together. In order to elimi-
nate external pull-up and pull-downs, one device
in a bank is designated as the default driver. For
non-SEARCH cycles or SEARCH cycles with a
global miss the SSF and SSV signals are driven by
the device with the LDEV Bit set.
Note:
It is important that only one device in a bank
of search engines that are cascaded together
have this bit set. Failure to do so will cause conten-
tion on SSV and SSF and can potentially cause
damage to the device(s).
