Abstract: An integrated circuit memory includes a logic circuitry bonded to a memory array. For example, the logic circuitry is formed separately from the memory array, and then the logic circuitry and the memory array are bonded. The logic circuitry facilitates operations of the memory array and includes complementary metal-oxide-semiconductor (CMOS) logic components, such as word line drivers, bit line drivers, sense amplifiers for the memory array. In an example, instead of being bonded to a single memory array, the logic circuitry is bonded to and shared by two memory arrays. For example, the logic circuitry is between two memory arrays. Due to the bonding process, a bonding interface layer is formed. Thus, in such an example, a first bonding interface layer is between the logic circuitry and a first memory array, and a second bonding interface layer is between the logic circuitry and a second memory array.

Abstract: The present disclosure relates to providing a wordline bridge between wordlines of adjacent tiles of memory cells to reduce the number wordline staircases in 3D memory arrays. An apparatus may include a memory array having memory cells. The memory array includes a first block of pages of the memory cells in a first tile and a second block of pages of the memory cells in a second tile. The apparatus may also include a polysilicon wordline bridge that couples first wordlines of the first block to second wordlines of the second block to couple the first tile to the second tile. The wordline bridge may be formed by applying a hard mask over the first tile, the second tile, and over a portion of polysilicon that connects the first tile to the second tile.

Abstract: A circuit includes (i) an N-channel device having a gate, a source connected to low voltage, and a drain connected to a memory select gate, (ii) a P-channel device having a gate, a source, and a drain connected to the drain of the N-channel device, and (iii) a voltage supply connected to the source of the P-channel device, the voltage supply switching between a first high voltage and a first lower voltage. A gate driver supplies, to the gates of the N-channel and P-channel devices, a second high voltage, a second low voltage, or an intermediary voltage between the second high voltage and second low voltage. The gate driver supplies the intermediary voltage when the voltage supply switches between the first high voltage and first lower voltage.

Abstract: An integrated circuit (IC) memory device having an interface coupled with a volatile random access memory (RAM) array and a nonvolatile flash memory array. Data to be written from an external device to the IC memory device is initially written to the volatile RAM array to provide for fast execution of a write operation, and is then written from the volatile RAM array to the nonvolatile flash memory array via the interface in a manner that is relatively transparent to external devices and the user. The interface may be configured to transfer data from the volatile RAM array to the external device if a read request matches an address tag field stored in the volatile RAM array. Data from first and second block addresses in the volatile RAM array and flash memory array may be merged in a flash merge buffer, and validity bits may be used to ensure that potentially stale data in the flash memory array is not used and that data coherency is maintained.

Abstract: A method, apparatus, and system for controlling the voltage levels across capacitors coupled between a first node and a second node of an integrated circuit so that the voltage levels across these capacitors will not exceed the breakdown voltage limitation of these capacitors. The voltage level between the first and second nodes of the integrated circuit can vary from a second voltage level to a first voltage level when the integrated circuit transitions from a second power state to a first power state, respectively. A first capacitor and a second capacitor are connected in series between the first and second nodes of the integrated circuit forming a middle node between the first and second capacitors.
