Once data has been written in DRAM, charges stored in each capacitor must maintain more than the refresh time so that the information stored in each DRAM cell can be read out correctly.
数据一旦被写进DRAM，每个小电容上电荷的存储时间就必须大于DRAM的刷新脉冲时间，如果由于漏电流致使存储的电荷丢失，就会导致数据读取的误操作。
The matching values indicate that the data has not changed since the time it was read.
双方的值如果相符，就表示资料从读取出来以后都没有变动过。
It can also be used as a standalone EEG recorder, whose data is stored in Flash Memory in real time and read out off line by a home PC.
或者作为EEG数据记录器单独使用，此时数据被实时地存储在自身的固态存储器内，供离线时被电脑读取。
