Protected electronic mass memory unit including first and second buses of the parallel type

摘要

A dual-access protected electronic mass memory unit, the various elements of which comprise a plurality of logic boards connected to at least one peripheral controller (CNT1, CNT2) of the information processing system (H) to which the unit belongs. The electronic memory unit includes at least one electronic disk unit (DEI1, DEI2) including a motherboard (11, 21) containing the corresponding controller (CNT1, CNT2), and a plurality of daughter boards (12-13, 22-23) comprising an equal number of memory planes connected among one another two-by-two, the first of them being connected to the motherboard. The central processor and the electronic disk unit are connected by the motherboard to a first and second parallel bus (B1, B2).
