Title: Adding and subtracting device
Inventor: HAGIWARA YOSHIMUNE
IPC: G06F7/50
Filed: 1989-07-21
Abstract: PURPOSE:To prevent an overflow and an underflow which accompany addition and subtraction from occurring by equipping a means which normalize an addition/subtraction result with a means which limits the shift quantity of the mantissa part of the addition/subtraction result so that the value of the exponent part is within a specific range. CONSTITUTION:A zero detecting circuit 79 and a left-directional shifting circuit 76 are provided so as to normalize the output UM of an adder 75 so that its absolute value is maximum. Namely, the zero detecting circuit 79 detects the number of theta1 of successive '0's following the sign bit of the data UM (below the decimal point) and the shifting circuit 76 shifts the data UM left (to the most significant digit bit) by theta1 bits to obtain mantissa part data LM which has the maximum absolute value. When the data UM is minus, on the other hand, the data is shifted only by the number of successive '1's. In this case, a subtracting circuit 78 calculates (gamma-theta1) as to exponent part data gamma and its output UE is regarded as a normalized exponent value. Consequently, a fast, high-accuracy OR arithmetic function is obtained.

Title: Nonvolatile semiconductor device and fabrication thereof
Inventor: IWASA SHOICHI
IPC: H01L29/792
Filed: 1993-06-30
Abstract: PURPOSE:To prevent write disturb by employing an NOR type bit contactless cell and suppressing the fluctuation of writing time between the memory cells of an EEPROM in Virtual Ground Memory array. CONSTITUTION:P-wells 16 made in an SOI substrate are isolated electrically for each memory cell in the direction of a word line 4. In the direction of a bit line 6, an N-type diffusion layer 3 is formed continuously to constitute a second bit line and the P-wells 16 are formed continuously for a predetermined number of memory cells and connected electrically with the bit line 6 through select transistors thus constituting a first bit line. At the time of erase and write operations, the first bit line functions as a select line along with the word line 4 and the second bit line functions as the select line only at the time of read operation when high voltage is not applied. Erasure and writing are effected through FN tunneling and electrons communicate between a floating gate 11 and the P-well 16 over the entire surface of channel region.

Filed: 1980-12-29
Abstract: PURPOSE:To realize the use of a chip having a partial defect, by using a compensating chip of the small capacity which is nearly equal to the width of the defective address region of a defective chip. CONSTITUTION:The memories of a partical defective memory chip 128 have the same address region. A program circuit 120 is programmed to indicate the defective block of the chip 128. A defect block address line 104, i.e., an output line of the circuit 120 shows the address of the defective block at all times. An upper address is first supplied to an input line 103 to be amplified by a buffer 121 as well as to be fed to memory chips 128 and 129, an address latch 124 and a comparator 122 respectively. The comparator 122 discriminates whether the input address is that of the defective block or not and then decides to give an access to the chip 128 or a defect compensating memory chip 129.
