Memory array architecture supporting block write operation

Abstract

A memory array architecture that supports block write operation and has many advantages over conventional memory array architectures. A memory array is partitioned into a number of (N) segments. Each segment includes at least one bit line. Each segment is associated with a local input/output (I/O) line that couples to zero or more bit lines within that segment. The bit lines are coupled to the local I/O line by controlling one or more column select lines associated with that segment. Each segment is also associated with a write driver that couples to the local I/O line. Each local I/O line has a length that is a portion of a length of the memory array. A block write operation is performed by concurrently driving one or more write drivers (up to N write drivers). Each write driver drives the bit lines coupled to the local I/O line associated with that write driver.

Dependencies are inferred from the claim text.
