Auto-precharge for a memory bank stack

Abstract:

Devices and methods include a command interface configured to receive commands, such as a write with an automatic precharge. A bank-specific decoder decodes the write with an automatic precharge command for a corresponding memory bank and outputs a write auto-precharge (WrAP) signal. This WrAP signal has not been adjusted for a write recovery time for the memory bank. Accordingly, bank processing circuitry in a bank receiving the WrAP signal uses the WrAP to cause its internal lockout circuitry to apply a tWR lockout based at least in part on a mode register setting and on the WrAP signal indicating receipt of the write with an automatic precharge command.
