制造商:
Integrated Silicon Solution(ISSI)
分类:
RAM芯片
封装:
TSOP-54
描述:
RAM， ISSI**ISSI** **SDR SDRAM** 系列提供同步接口，具有可编程 CAS 等待时间（2/3 时钟）。 可使用管道流程实现高速数据传输，且同步 DRAM SDR 系列可提供脉冲读/写功能，且脉冲读/单写入使其特别适用于计算机应用。 **ISSI** SDR SDRAM 设备提供不同的组织和存储器大小系列，工作电源为 3.3V。 LVTTL 接口 有关输入/输出信号，请参考时钟输入的上升边缘 可编程脉冲序列：连续/交错；可编程脉冲长度 每个时钟周期的随机列地址 自刷新和自动刷新模式 ### 动态 RAM
