Memory term explanation CAS
CAS is intended to column Address Strobe or Column Address Select, CAS controls the interval time of receiving the command to the execution command, usually 2, 2.5, 3 this few clock cycles. In the entire memory matrix, because the CAS is managed by the column address, this very important parameter value is based on the basis, the lower the better. The process is like this, divided into rows and columns in the memory array. After the command requests to reach the memory, the triggered TRAS (Active to Precharge DELAY), the data is required to be charged, once the TRAS is activated, RAS I started to add to half of the physical address. After the line was selected, TRCD initialized, and finally found an exact address through CAS. The entire process is the first addressing and column addressing. From CAS to CAS, it is a CAS latency now. Because CAS is the last step of addressing, it is most important in the memory parameter.
