Abstract: An example apparatus to monitor memory includes an error manager to compare a first memory location of a first error in the memory to a plurality of memory locations in an error history log, the plurality of memory locations previously identified in the error history log based on errors detected in the memory locations, ones of the memory locations associated with corresponding counters that track the errors detected in the memory locations, and update a first one of the counters corresponding to the first memory location when a first address of the first memory location matches a second address of one of the memory locations in the error history log. The example apparatus further includes a command generator to transmit a command to an error corrector to perform error correction on the first memory location when the first one of the counters satisfies a threshold.

Abstract: Logic may store data structures for two or more processors in memory such as cache, system management memory, protected memory, or other memory. Logic may compress the data structures to be stored in the memory. Logic may determine a reference data structure, store the reference data structure in the memory, determine a difference between a data structure for a second processor and the reference data structure, and store the difference in the memory. Logic may store the difference in the memory within a data structure such as a linked list or a bitmap. Logic may decompress the difference by combining the difference with the reference data structure. Logic may expand the useable data region to include cache in the two or more processors. Logic may instruct two or more processors to store their processor data structures in their respective caches and perform initialization with the processor data structures.
