Integrated circuits with memory circuitry are provided. The memory circuitry may include rows of data line segments. Each data line segment may have associated memory cells, a programmable-strength precharge circuit, a latch circuit, a programmable-strength pull-up circuit, and a data line segment buffer. The precharge circuit may include multiple paths that can be switched into use depending on the configuration of programmable bits. The programmable-strength pull-up circuit may include multiple pull-up paths. The number of pull-up paths in use can be configured. The latch circuit may include a latch inverter that enables the programmable latch circuit during precharge operations. During a precharge period, the latch circuit can be disabled to block contending pull-down current and the data line segment buffer can be disabled to avoid crossbar currents. |
