|
|
|
| MCB1_A4 | E18 | Address inputs: Provide the row address for ACTIVE commands, and |
| |
| MCB1_A5 | L12 | the column address and auto precharge bit (A10) for READ or |
|
|
|
|
| WRITE commands, to select one location out of the memory array in |
| |
| MCB1_A6 | L13 |
| ||
| the respective bank. During a PRECHARGE command, A10 |
|
| ||
| MCB1_A7 | F17 | determines whether the PRECHARGE applies to one bank (A10 |
|
|
|
|
| LOW, bank selected by BA0, BA1) or all banks (A10 HIGH). The |
|
|
| MCB1_A8 | H12 |
|
| |
| address inputs also provide the |
|
| ||
| MCB1_A9 | G13 | REGISTER command. |

|
| READ, WRITE, or PRECHARGE command is being applied. BA0 |
| |
| MCB1_BA1 | H14 | and BA1 also determine which mode register is loaded during a |
|
|
| LOAD MODE REGISTER command. |
