| 发明名称 | Signal tracking in write operations of memory cells | ||
| 摘要 | In a method, a first edge of a first tracking signal in a first direction of a memory array is generated. A first edge of a second tracking signal in a second direction of the memory array is generated. A first edge of a write-timing control signal is generated based on a slower edge of the first edge the first tracking signal and of the first edge of the second tracking signal. The first edge of the write-timing control signal is used to generate a second edge of the second tracking signal. | ||

| 主权项 | 1. A method comprising: generating a first edge of a first tracking signal in a first direction of a memory array; generating a first edge of a second tracking signal in a second direction of the memory array; and generating a first edge of a write-timing control signal based on a slower edge of the first edge of the first tracking signal and the first edge of the second tracking signal, wherein the first edge of the write-timing control signal is used to generate a second edge of the second tracking signal. | ||
