【产品】8n-位预取架构的DDR4 SDRAM AS4C1G16D4,电源电压1.2V±60mV
ALLIANCE推出的DDR4 SDRAM AS4C1G16D4是一款高速动态随机存取存储器,内部配置为x16配置的8块动态随机存取存储器。DDR4 SDRAM采用8n-预取架构,实现高速运行。8n-预取架构与一个接口相结合,该接口每个时钟周期可在I/O引脚处传输两个数据字。
DDR4 SDRAM的单个读或写操作由内部DRAM核心上的单个8n-位宽、四时钟的数据传输和在I/O引脚上的两个对应的n-位宽、一个半时钟周期的数据传输构成。
单个商用温度器件选项要求外壳温度不低于0℃或高于95℃。JEDEC规格要求TC超过85°C时刷新率翻倍;也需要使用高温自我刷新选项。
