Abstract: An apparatus for page-copy data accessing is provided, which includes a memory cell array, bit-line sense-amplifier/buffers (BLSABFs), page buffers and a logic operation processing circuit. Data voltage signals on bit-lines in a memory section are transferred to the bit-lines in an adjacent memory section adjacent to the memory section by BLSABFs and the voltage data signals are sequentially propagated across subsequent memory sections through BLSABFs between the subsequent memory sections. 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 target location to write voltages to the memory cells at the target location. The page buffers are configured to receive data voltage signals from the coupled BLSABFs to a data interface.

Abstract: Page data can be propagated sequentially from a section to the neighboring section, and from this section to subsequent section adjacent to it until a page register set is reached. In a described apparatus based on this page-data-copy scheme, access data from a page register (which is also used for storing the data accessed using the page-data-copy scheme) with a conditional read-access method in conjunction with an arithmetic unit can execute the arithmetic process of an AI system.
