In the prior art, DRAMs (Dynamic Random Access Memories) are used to store and reproduce digital data, or ARAMs (Audio Random Access Memories) are used to store and reproduce speech. The components are expensive and lose their stored data if the power fails. The present device and method uses electrically erasable, programmable read-only-memories, the so-called EEPROMs (Electrically Erasable and Programmable Read Only Memories), in a block structure for mass storage applications with control software. A digital signal processor (DSP) is directly connected to the read-only-memory (EEProm), which is partitioned into segments. Software drivers in the digital signal processor (DSP) enable the segment by segment writing and reading between the digital signal processor and the read-only-memory.
