Abstract
A semiconductor memory apparatus is capable of improving the alignment margin for a bank and sufficiently ensuring a space for forming a global input/output line. The semiconductor memory apparatus includes a stack bank structure having at least two sub-banks continuously stacked without disconnection of data signal lines, and a control block arranged at one side of the stack bank structure to simultaneously control column-related signals of the sub-banks.
Claims4
A semiconductor memory apparatus comprising:
- a plurality of stack bank structures, the plurality of stack bank structures being spaced apart from each other at a predetermined interval and including a plurality of sub-banks;
- a plurality of control blocks, wherein each control block configured to control all column-related signals of the plurality of sub-banks constituting each stack bank structure;
- and
- a plurality of global input/output lines arranged between the stack bank structures,
- wherein each of the plurality of control blocks includes an address control block and an Input/Output control block, the address control block is arranged between the plurality of sub banks constituted in each of the plurality of stack bank structures, the Input/Output control block is arranged at one side of each of the plurality of stack bank structures, and the address control block includes a main decoder and a predecoder.
