Abstract
A self-identifying scheme which permits a variety of integrated circuit semiconductor memory modules to inform a host processor as to each individual memory accessing speed or accessing time. Pre-encoded circuits within each memory module generate a coded signal when that module is selected by the host processor. The coded signal identifies the type of memory accessed, permitting the host processor to transfer information at a rate determined by the memory accessed.
