FIELD: circular memory technologies.
SUBSTANCE: into memory cell, containing the oldest data record, new data record is placed and then pointer is renewed, while aforementioned pointer has first pointer (P1,P1*) and second pointer (P2,P2*), being excessive relatively to first pointer, each of these pointers has control number in form of additional or reversed code of the same pointer.
EFFECT: development of method and circular memory for reliable recording of pointer.
