Abstract:
Voltages loaded onto the bit lines in a first CA section of a memory array can be latched by enabling the BLSA between the first section and a second section adjacent to the first section causing latched voltages to propagate to bit lines in the second section. Voltages propagated to the bit lines in the second section using the latches between the second section and a third section. Voltages can be propagated sequentially from section to subsequent adjacent section until a target location is reached. The scheme can be applied as a method of page-data write access in a memory chip, of which page data can be propagated sequentially from section to subsequent adjacent section until a target location is reached, and then, activating a word line in a section of the memory comprising the target location to write voltages to the memory cells at the target location.
