This document describes both the 82434LX and 82434NX Unshaded areas describe the 82434LX
Shaded areas like this one describe 82434NX operations that differ from the 82434LX
The 82434LX 82434NX PCI Cache Memory Controllers (PCMC) integrate the cache and main memory
DRAM control functions and provide bus control for transfers between the CPU cache main memory and the
PCI Local Bus The cache controller supports write-back (or write-through for 82434LX) cache policy and
cache sizes of 256-KBytes and 512-KBytes The cache memory can be implemented with either standard or
burst SRAMs The PCMC cache controller integrates a high-performance Tag RAM to reduce system cost
