  • Publication number: 20190311255
    Abstract: Inspired by the processing methods of biologic brains, we construct a network of multiple configurable non-volatile memory arrays connected with bus-lines as a neuromorphic code processor for code processing. In contrast to the Von-Neumann computing architectures applying the multiple computations for code vector manipulations, the neuromorphic code processor of the invention processes codes according to their configured codes stored in the non-volatile memory arrays. Similar to the brain processor, the neuromorphic code processor applies the one-step feed-forward processing in parallel resulting in a dramatic power reduction compared with the computational methods in the conventional computer processors.

  • Patent number: 10431308
    Abstract: Scalable Logic Gate Non-Volatile Memory (LGNVM) NOR-type arrays fabricated by the standard CMOS logic technologies have been applied for the embedded flash solutions in digital circuitries. To significantly reduce the memory array sizes from the previous fabrications, we have applied the topological regularity of memory cells in the arrays and a self-aligned etch process step to eliminate the gate end-caps in the memory areas. Without scarifying the memory array yields, the minimal unit cell size of 12 F2 for the LGNVM NOR flash arrays can be achieved by this method, where F is the minimal feature size for a specific CMOS logic process technology node.

  • Patent number: 10147492
    Abstract: A non-differential sense amplifier circuit for reading out information in Non-Volatile Memories (NVMs) is disclosed. The circuit comprises a half latch, a PMOSFET device, a switch device and a reset transistor. The PMOSFET device has a source electrode connected to a digital voltage rail, a drain electrode connected to an output node of the half latch and a gate electrode connected to a bitline path coupled with a selected NVM cell. After the bitline path is pre-charged and the reset transistor is turned off, applying a read voltage to a word line related to the selected NVM cell causes a voltage at the gate electrode of the PMOSFET device to drop differently according to an electrical conductance state of the selected NVM cell. The disclosed circuitries can achieve extra low power consumption and high sensing speed compared to those in the conventional sensing scheme.

  • Patent number: 10148254
    Abstract: The standby leakage current reduction schemes for digital data storing components are disclosed. By floating the low digital voltage node of the digital data storing components in standby mode, the major standby leakage current paths to the ground voltage caused by the channel diffusion leakage current of MOSFET devices can be terminated. The standby leakage currents will be reduced to the small reverse junction leakage currents to the grounded substrate. For retaining the stored data in the digital data storing components in standby mode, the low digital voltage node is connected to the ground voltage periodically according to a plurality of rectangular voltage pulses outputted from a pulse generator trigged by a low frequency clock oscillator. Due to no external voltage bias to the low digital voltage node other than floating the digital low voltage node, the data recovering process is instant.

  • Patent number: 10068772
    Abstract: A recess channel semiconductor non-volatile memory (NVM) device is disclosed. The recess channel MOSFET devices by etching into the silicon substrate for the device channel have been applied to advanced DRAM process nodes. The same etching process of the recess channel MOSFET device is applied to form the recess channel semiconductor NVM device. The tunneling oxides are grown on silicon surface after the recess channel hole etching process. The storing material is deposited into the recess channel holes with coupling dielectrics on top of the storing material. The gate material is then deposited and etched to form the control gate. Owing to the recess channel embedded below the silicon substrate, the scaling challenges such as gate channel length, floating gate interference, high aspect ratio for gate stack etching, and the mechanical stability of gate formation for the semiconductor NVM device can be significantly reduced.

  • Patent number: 9685239
    Abstract: A Field Sub-bitline NOR-type (FSNOR) flash array and its operating methods are disclosed. In contrast to the conventional NOR flash array, the FSNOR array is configured in column with multiple 90° rotated NOR pairs linked by field side sub-bitlines to achieve the minimum 4F2 cell size. The FSNOR flash array is divided into multiple sectors by selection transistors for connecting the even/odd sub-bitlines to the global main first metal bitlines. For each FSNOR sector, the two drain electrodes of column-adjacent NOR pairs form the even/odd sub-bitlines separated by trench field oxides respectively, and the common source electrodes of NOR pairs in a column form the common diffusion source lines tied with metal contacts connected to the first metal common source lines. The FSNOR flash array design has enhanced the electrical isolation of the selected NVM cell devices from the unselected NVM cell devices.

  • Patent number: 9595330
    Abstract: A Configurable Non-Volatile Content Addressable Memory (CNVCAM) cell consisting of a pair of complementary non-volatile memory devices and a MOSFET (Metal-Oxide-Semiconductor-Field-Effect-Transistor) is disclosed. The CNVCAM cells can be constructed to form the NOR-type match line memory array and the NAND-type match line memory array. In contrast to the Random Access Memory (RAM) accessed by the address codes with the prior knowledge of memory locations, CNVCAM can be pre-configured into non-volatile memory content data and searched by an input content data to trigger the further computing process. The unique property of CNVCAM can provide a key component for neural computing.
