A memory access method includes: data storage instructing of issuing a data storage instruction instructing that, in accordance with a first logical address, one item of data be stored into a first memory or a second memory; and first storage path selecting of performing, in response to the data storage instruction, first selecting of selecting whether to execute first storing or second storing based on the first logical address included in the data storage instruction. In the first storage path selecting, the first selecting is performed based on a first interleave rule or a second interleave rule. The first selecting is performed based on the first interleave rule in response to one or more data storage instructions, and the first selecting is performed based on the second interleave rule in response to subsequent one or more data storage instructions.

Polymers of C4 olefins having a viscosity of 15 to 35 centistokes at 100.degree. F show improved performance as cosmetic oils, in comparison with squalane. These polymers are prepared by polymerizing (a) isobutylene by itself, or (b) C4 hydrocarbon olefin containing a mixture of at least two of isobutylene, 1-butene, 2-butene and butadiene, using a catalyst; then removing high molecular weight and low molecular weight compounds by distillation; hydrogenating the remainder of the polymerization product; removing carbonyl compounds therefrom if necessary and further purifying the resultant polymer by steam distillation or treating same with activated carbon or solvent extraction, to deodorize same.
