Circuitry for data storage, especially dynamic random access memory (DRAM) with flexibly arranged circuit chips for memory cell units and data transmission units, without faults in units causing total breakdown of entire circuitry

摘要

Circuitry comprises memory cell unit (101), e.g. DRAM, with memory cell field for storage of electric charges, data transmission unit (102) for data transmission between memory cell unit and external circuit units. Connector units (104a-n) provide electric link for external circuit units to data transmission unit. Memory cell unit and data transmission unit are arranged on separate chips, with their electric connection escured by coupling unit (103).
