    • A system and method for providing a constant electric field that is insensitive to fluctuations in the power supply to a FLASH EPROM during erasure. The system comprises a plurality of sector source drivers and a power supply insensitive constant current source. Each sector has at least one binary storage element. Each storage element has a source. The sector source drivers couple the at least one source of a sector to be erased to the power supply insensitive constant current source. The power supply insensitive constant current source provides an electric field across the tunneling oxide which is constant and insensitive to fluctuations in the power supply. This improves the wear characteristics and lifetime of the binary storage elements. In addition, this system remedies problems associated with short channel effects, electron trapping, and the use of various voltage sources.

    • The present invention provides a method for fabricating small structures to be employed in integrated circuits formed on a semiconductor substrate. Examples of such small structures include contacts, vias, and metal lines. The method of the present invention employs an image reversal technique to obtain improved feature definition. In forming a feature in a layer of material, a clear field reticle is used to form patterned segments of photoresist each having a size, a shape, and a location substantially identical to the size, the shape, and the location of one of the features intended to be formed in the layer of material. This method is employed instead of using a dark field reticle which forms windows in a photoresist each having a size, a shape, and a location substantially identical to the size, the shape, and the location of one of the features intended to be formed in the layer of material. For small structures, the openings or windows in a photoresist are harder to form than the patterned segments of photoresist. With the method of the present invention which employs a clear field reticle to form a mask comprising patterned segments of photoresist, the limitations of patterning small windows in a photoresist with the use of a dark field reticle are avoided. The accuracy of forming the small structures is thus improved.

    • Disclosed herein is a channel hot-carrier page write including an array of stacked gate flash EEPROM memory cells operating in a very low energy programming mode permitting page writing of 1024 bits within a 20-100 mu S programming interval. Internal programming voltage levels are derived from on-chip circuits, such as charge pumps, operated from a single +VCC source. In a preferred embodiment, a cache memory buffers data transfers between a computer bus and the page oriented storage array. In another embodiment, core doping is increased in the channel and drain regions to enhance hot carrier injection and to lower the programming drain voltage. The stacked floating gate structure is shown to exhibit a high programming efficiency in a range from 10-6 to 10-4 at drain voltages below 5.2 VDC. In another embodiment AC components of the programming current are minimized by precharging a common source line at the start of a programming cycle.

    • When a data input signal having R plus X groups of M digits is received, the digits are segmented such that X different first counter-detectors receive M digits and a second counter-detector receives the R digits. The counter-detectors determine a number of most significant count digits leading a most significant non-count digit and detect the presence of a non-count digit. A decoder receives the outputs of the first counter-detectors and, responsive to a non-count digit detection in a most significant group of M digits having a non-count digit, communicates the corresponding count number to a concatenator. A third counter-detector determines and communicates a number of most significant groups of M digits having no non-count digits. An output of the third counter detector is concatenated with an output of the decoder where the decoder output is represented by Z digits where M=N (X, M, R, N, and Z are non-negative integers). The concatenation represents the number of leading count digits. If R is non-zero, the second counter-detector determines a number of most significant count digits leading a most significant non-count digit and detects the presence of a non-count digit in the R most significant bits. An adder then adds R to the concatenation. A multiplexer selects the number of leading count digits in the R bits if the R bits contain a non-count digit else the multiplexer selects the concatenation plus R.
    • 当接收到具有R加X组M位的数据输入信号时,这些数字被分段,使得X个不同的第一反侦测器接收M个数字,而第二个反侦测器接收R个数字。 反检测器确定导致最重要的非计数位数的最重要的计数位数,并检测非计数位的存在。 解码器接收第一反检测器的输出,并且响应于具有非计数位的最高有效M位组中的非计数位检测,将相应的计数编号传送给连接器。 第三个反检测器确定并传送不具有非计数位数的M位数的最重要组。 第三计数器检测器的输出与解码器的输出连接,其中解码器输出由Z位表示,其中M = N< Z> (X,M,R,N和Z是非负整数)。 连接表示前导计数位数。 如果R不为零,则第二个计数器检测器确定最高有效计数位的数量,并导致最重要的非计数位,并检测R个最高有效位中是否存在非计数位。 然后加法器将R添加到串联中。 如果R位包含非计数位,则多路复用器选择R位中的前导计数位的数量,否则多路复用器选择级联加R。 <图像>

    • A superscalar complex instruction set computer ("CISC") processor (100) having a reduced instruction set computer ("RISC") superscalar core (110) includes an instruction cache (104) which identifies and marks raw x86 instruction start and end points and encodes "pre-decode" information, a byte queue (106) which is a queue of aligned instruction and pre-decode information of the "predicted executed" state, and an instruction decoder (108) which generates type, opcode, and operand pointer values for RISC-like operations (ROPs) based on the aligned pre-decoded x86 instructions in the byte queue. The instruction decoder includes in each dispatch position a logic-based conversion path (712, 722, 732, 742), a memory-based conversion path (716, 726, 736, 746), and a common conversion path (714, 724, 734, 744) for converting CISC instructions to ROPs. An ROP multiplexer (400) directs x86 instructions from the byte queue to the conversion paths. The ROP multiplexer includes scan logic (690) which rapidly scans the byte queue to generate for each dispatch position an array of bits (ISELx) that identifies the location of the opcode, and ROP information signals (ROPxNUM, ROPxDIFF, PGNXTÄxÜ). The scan logic is segregated into groups of bit processing logic (GP(x,y)) and includes a look-ahead capability (LAG(x)) between groups.
