在日本国内外,目前有10家以上的公司正在同时研制可能应用于图象领域的随机存取和串行存取的专用256k位动态存储器。日本电气公司以位影象显示的帧缓冲器为目标,已经有样品出售。这种产品中,想把用于该领域的存储器从64k转向256k。国际标准化工作也在进行中。24引线的64k×4位结构和22引线的256k×1位结构的两种方案都有可能在1985年中采用。研制专用动态存储器的高潮已经到来。 At home and abroad in Japan, more than 10 companies are simultaneously developing dedicated 256k bits of dynamic memory that may be used for random access and serial access in the graphics area. Nippon Electric Co., Ltd. targets a frame buffer for image display, and samples have already been sold. In this product, you want to shift the memory used in this area from 64k to 256k. International standardization work is underway. Both the 64-k × 4-bit structure of the 24-lead and the 256k × 1-bit structure of the 22-lead are likely to be adopted in mid-1985. The climax of the development of dedicated dynamic memory has arrived.
