Abstract
A memory device includes transistors and a memory cell array disposed over and electrically coupled to the transistors. The memory cell array includes word lines, bit line columns, and data storage layers interposed between the word lines and the bit line columns. A first portion of the word lines on odd-numbered tiers of the memory cell array is oriented in a first direction, and a second portion of the word lines on even-numbered tiers of the memory cell array is oriented in a second direction that is angularly offset from the first direction. The bit line columns pass through the odd-numbered tiers and the even-numbered tiers, and each of the bit line columns is encircled by one of the data storage layers. A semiconductor die and a manufacturing method of a semiconductor structure are also provided.
