25. 7. 90 Official  Journal of the European Communities No L 193/1 (Acts whose publication is obligatory) COUNCIL REGULATION (EEC) No 2112/9¢ of 23 July 1990 imposing a definitive anti-dumping duty on imports of certain types of electronic microcircuits known as DRAMs (dynamic random access memories) originating in Japan and collecting definitively the provisional duty THE COUNCIL OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Economic Community, Having regard to Council Regulation (EEC) No 2423/88 of 11 July 1988 on protection against dumped or subsi- dized imports from countries not members of the Euro- pean Economic Community (), and in particular Articles 9 and 12 thereof, Having regard to the proposal submitted by the Commis- sion after consultations within the Advisory Committee as provided for by the above Regulation, Whereas, A. Provisional measures (1) The . Commission, by Regulation (EEC) No 165/90 (3, imposed a provisional anti-dumping duty on imports of certain types of electronic microcircuits known as DRAMs - (dynamic random access memories) originating in - Japan, accepted undertakings offered by certain exporters in connection with the anti-dumping proceeding concerning imports of - these products. and - ter- minated the investigation in this respect. The Commission . subsequently published two corri- genda to - this Regulation (). Furthermore, the validity of the provisional duty was extended for-a period not exceeding two months by Council Regulation (EEC) No 1361/90 (4. B. Subsequent procedure (2)  Following the imposition of the provisional anti- dumping duty, one independent importer which had not previously made itself known, requested, and was granted, an-opportunity to be heard orally by the Commission-and made its views known in () OJ No L 209, 2. 8. 1988, p. 1. () OJ No L 20, 25. 1. 1990, p. 5. () OJ No L 22, 27. 1. 1990, p. 79 (English edition only). OJ No L 38, 10. 2. 1990, p. 44. () OJ No L 131, 23. 5. 1990, p. 6. writing. One Japanese producer/exporter also made its views known in writing. (3) Several  Japanese  producers/exporters. have requested that further related companies be added to the list contained in Annex I to Regulation (EEC) No 165/90. (4)  The oral and written submissicns and comments of the parties were considered and, where appropriate, the Commission’s findings were modified to take account of them. (5 Due to the complexity of the DRAM industry, in particular the internationalization of manufacturing processes, the huge volume of data to be processed and verified and the numerous arguments put’ forward, this investigation could not-be concluded within the time provided for in Atticle 7 (9) (a) of Regulation (EEC) No 2423/88. C. Products under investigation, like products and Community industry (a) Products under investigation (6)  The products under investigation are certain types of electronic microcircuits : known as dynamic random access memories: (DRAMs) (") whether assembled, in processed wafer or dice form, manu- factured using variations of metal oxide semicon- ductor (MOS) process technology including () A DRAM is a monolithic integrated memory circuit contain- ing thousands of memory storage cells (bits) each of which " contains a transistor and capicitor. A stored programme can be created in the DRAM by charging selected capacitors. The storage cells in a DRAM are arranged in a rectangular array of - columns and rows; which allows each cell to be accessed inde-- pendently (random access). The electrical charge stored on the cells must be regenerated after being accessed, and periodical- ly because of leakage. The required regeneration of the charge on the capacitors makes the device ‘dynamic’. DRAMs vary, inter alia, in the speed at which the storage cells can be ac- cessed (access time) and in the amount of information that can be stored (density) expressed as multiples of 1 024 capaci- tors, kilobits or K.
