摘要:
The disclosure provides a semiconductor structure, a layout of the semiconductor structure and a semiconductor device. The semiconductor structure includes: a plurality of first conductive layers that are spaced; a plurality of capacitor banks, and the capacitor bank being on the first conductive layer in one-to-one correspondence and the capacitor bank including at least a capacitor, each capacitor including a lower electrode layer, a capacitance dielectric layer and an upper electrode layer stacked from bottom to top; a capacitor plate, wherein the capacitor plate is on each upper electrode layer; and a second conductive layer, wherein the second conductive layer is above the capacitor plate and connected with the capacitor plate. In the above semiconductor structure, the second conductive layer is formed above the capacitor plate, and the second conductive layer is connected with the capacitor plate, so that in the semiconductor structure, the second conductive layer is equivalent to being connected in parallel at two ends of the capacitor plate, that is, the second conductive layer is connected with the capacitor plate in parallel, and the resistance formed by the parallel connection of the second conductive layer and the capacitor plate is lower than the resistance of the capacitor plate itself, thereby avoiding the problem of affecting the performance due to the high resistance and improving the performance of the semiconductor structure.

Examples are disclosed for accessing a dynamic random access memory (DRAM) array. In some examples, sub-arrays of a DRAM bank may be capable of opening multiple pages responsive to a same column address strobe. In other examples, sub-arrays of a DRAM bank may be arranged such that input/output (IO) bits may be routed in a serialized manner over an IO wire. For these other examples, the IO wire may pass through a DRAM die including the DRAM bank and/or may couple to a memory channel or bus outside of the DRAM die. Other examples are described and claimed.

A technique includes determining, via an analog circuit, where an access rate of a memory row associated with a memory device exceeds a threshold. In various examples, upon a determination that the access rate exceeds the threshold, the technique may further comprise generating an alert to indicate possible corruption of data stored in an adjacent row to the memory row.

Embodiments of the invention describe systems, methods, and apparatuses to reduce the instantaneous power necessary to execute a DRAM device initiated self-refresh. Embodiments of the invention describe a DRAM device enabled to stagger self-refreshes between a plurality of banks. Staggering self-refreshes between banks reduces the current required for a DRAM self-refresh, thus reducing the amount of current required by the DRAM device.

A memory system supports high-performance and low-power modes. The memory system includes a memory core and a core interface. The memory core employs core supply voltages that remain the same in both modes. Supply voltages and signaling rates for the core interface may be scaled down to save power. Level shifters between the memory core and core interface level shift signals as needed to accommodate the signaling voltages used by the core interface in the different modes.

A memory interface circuit includes a plurality of data bus drivers and logic adapted to be operatively responsive to write driver mask information. If desired, the plurality of bus drivers and the logic may be implemented in separate integrated circuits. The plurality of bus drivers are adapted to be responsive to a write operation. The logic is also adapted to disable any one of the plurality of data bus drivers based on the write driver mask information during the write operation.

A dynamic random access memory has logically identical circuits for providing the same logical control signals. Each set of control signals can have different electrical parameters. One circuit can be optimized for high speed performance, while another circuit can be optimized for low power consumption. The logically identical circuits can include wordline address predecoder circuits (400,402,404), where a high speed predecoder circuit (402) is enabled during a normal operating mode and a slower low power predecoder circuit (404) is enabled for self-refresh operations. During self-refresh operations, the high speed circuit (402) can be decoupled from the power supply to minimize its current leakage.
