Writing bit alterable memories

摘要

A bit alterable memory may include current generators in a periphery outside the main memory core. Current may be generated in the periphery and driven into the core. As a result, the capacitance of the memory cells has a lowered effect. The current may be generated using the chip supply voltage and then mirrored using a pump voltage. In some embodiments, the mirroring may be ratioed at the partition level and multiplied at the plane level. A delay may be provided before applying the currents to the cell to accommodate for transients.
