Abstract (in Japanese) (See Japanese page) 
(in English) In this study, we analyze stable states and retrieval dynamics of an autocorrelation associative memory model storing memory pattern with correlation structure by statistical mechanics and computer simulation.
Various correlation structure could be thought for the memory patterns,
but in this study, we use abstract memory pattern possessing two information such as the difference of the individual and the observation direction in human faces.
As the result of analysis,we found that there are several stable states,
one of them is memory pattern and the others are mixed states of the memory patterns.
Furthermore, there are several types of mixed state,one is a state possessing two information such as the difference of the individual and the observation direction,and the others are states with only one information of them.
We also found that even if the thermal fluctuation increases, the stability of the mixed state possessing two information does not change greatly.
Moreover, we show the retrieval dynamics of each stable states.
