实际上,Prefetch并不是什么新技术,在DDR1就开始应用了,我们以前经常能看到这样描述DDR,“在时钟周期的上沿和下沿都能传输数据,所以传输率比SDRAM快了一倍”,这就说上沿传输一位数据,下沿传输一位数据,在一个时钟周期内一共传输两位数据(2-bit),但这2-bit数据得先从存储单元预取出来才行(一个时间周期)。换句...
The DDR4 SDRAM is a high-speed dynamic random-access memory internally configured as sixteen-banks, 4 bank group with 4 banks for each bank group for x4/x8 and eight-banks, 2 bank group with 4 banks for each bankgroup for x16 DRAM. The DDR4 SDRAM uses a 8n prefetch architecture to a...
