Research & Development

Abstract

The emerging semiconductor memory technology over the last two decades has seen an accelerated growth in memory chip density and capacity against a background of falling costs in terms of pence per bit. In this, the first of two reports, the trends of this technology and some of the important operational characteristics of each ensuing generation of device are described. The design philosophy for forming the devices into useful tools for the storage of television signals is also outlined. In the second and companion Report, some of the applications as developed in Βι¶ΉΤΌΕΔ Research Department over the period 1975-1986 are described in detail. These include improved television synchronisers, high-quality PAL decoders, television noise reducers, film-dirt concealment equipment and buffer storage for television picture-processing equipment such as stills stores.
