M12L128168A-5TIG中文资料2M x 16 Bit x 4 Banks Synchronous DRAM数据手册ESMT规格书

描述 Description

GENERAL DESCRIPTION
The M12L128168A is 134,217,728 bits synchronous high data rate Dynamic RAM organized as 4 x 2,097,152 words by 16 bits. Synchronous design allows precise cycle control with the use of system clock I/O transactions are possible on every clock cycle. Range of operating frequencies, programmable burst length and programmable latencies allow the same device to be useful for a variety of high bandwidth, high performance memory system applications.FEATURES
