A non-volatile memory device and method for manufacture and programing which does not require a control gate for the programing or erasure of the device. The memory device is comprised of two wells with the opposite conductivity type of the semiconductor body. In one of the wells is a source and drain well of the same conductivity type as of the body. A oxide is formed on the surface of the body on which a floating gate is formed. Specific voltages are applied to the source, drain, first well and second well region to program, erase and read the memory device.

A data communication system and a data communication method are provided. The data communication system comprises a bidirectional cable, an antenna, a receiving and a function circuit block. The bidirectional cable transfers data through a high and a low frequency band. The antenna is to receive and transfer the analog data signal through the high frequency band of the bidirectional cable. The receiving circuit block comprises a receiving module to receive the analog data signal from the high frequency band and converts the analog data signal into a digital data to a host and a first control signal processing module to couple a control signal to the low frequency band. The function circuit block comprises a second control signal processing module to decouple the control signal from the low frequency band and a function module to perform an adjustment on the data communication system according to the control signal.

摘要:
Polysilicon or other material is directionally trimmed using two layers of photoresist and a photoresist etching process, such as ashing. A first layer of photoresist is patterned on a wafer. Portions of the first patterned photoresist are covered with a second layer of photoresist. The photoresist is trimmed to reduce the size of the exposed portions of the first patterned photoresist without reducing the size of the covered portions of the first patterned photoresist. The second layer of photoresist is removed. The selectively etched patterned first layer of photoresist is used as a process mask to define a structure in the underlying material. In a particular embodiment, the second photoresist covers endcap portions of gate photoresist. Directional trimming reduces the width of a polysilicon gate structure (i.e. gate length) over an active area of an FET, without reducing the length of original first patterned photoresist.

A nonvolatile memory cell which is highly scalable includes a cell formed in a triple well. A select transistor can have a source which also acts as the emitter of a lateral bipolar transistor. The lateral bipolar transistor operates as a charge injector. The charge injector provides electrons for substrate hot electron injection of electrons onto the floating gate for programming. The cell depletion/inversion region may be extended by forming a capacitor as an extension of the control gate over the substrate between the source and channel of said sense transistor.
