Refresh Cycles/64ms或8192 Refresh Cycles/64ms的标识,这里的4096与8192就代表这个芯片中每个Bank的行数。刷新命令一次对一行有效,发送间隔也是随总行数而变化,4096行时为15.625μs(微秒,1/1000毫秒),8192行时就为7.8125μs。HY57V561620为8192 refresh cycles / 64ms。

今天白天时为了搞明白第2个问题中REFRESH是如何设置的,我又把S3C2440和HY57V561620的规格书相关部分看了一遍。发现了 # if defined(CONFIG_S3C2440) #define Trp 0x2 /* 4clk */ #define REFCNT 1012 #else 这段设置中Trp的设置缘由。 S3C2440中REFRESH寄存器的描述部分有对Trp的说明如下: ...
