Filed: 1986-07-28
Abstract: PURPOSE:To execute a data dispersion test between a floating gate and a drain under the same state as a real writing state by providing the titled memory with dummy cells connected to plural normal unit memory cells in parallel and having the same structure and a dummy writing circuit having the same structure as a normal writing circuit. CONSTITUTION:At the time of executing a data dispersion test between the floating gate 2 and the drain 3, a normal writing transistor (TR) Q1, a Y selector TR Q2 and a memory cell group (Q3...Qn) are turned off, a dummy writing TR T1, a Y selector TR T2 and a memory cell T3 are turned on to write data in a dummy memory cell T3. Since the dummy writing circuit and the dummy memory cell T3 have the same structure respectively as the normal writing circuit and the normal memory cell, real writing current is the same as writing current flowing at the time of the dispersion test, so that the drain voltages of the normal and dummy memory cell groups are the same. Thereby, the data dispersion test between the floating gate and the drain can be executed under the same state as the practical writing state.

Title: Analog-to-digital converter
Inventor: HONDA MICHITAKA
IPC: H03M1/04
Filed: 1984-08-28
Abstract: PURPOSE:To simplify the circuit constitution and to improve the accuracy of an A/D converter by using an adder for output of the A/D converter, a register, a divider, a register storing previously the noise DC component and a subtractor which converts the output of the divider into digital signals. CONSTITUTION:The original input analog signal is converted into a digital signal of M-bit length by an A/D converter 1 and accumulated by an adder 2 and a register 3. When a satisfactory number of sample points are accumulat ed, the contents of the register 3 are sent to a divider 4 and divided by the number of sample points. In this case, upper L bits remain. The contents of these L bits are subtracted from the contents of a register 5 storing previously the noise DC component through a subtractor 6 and then transferred to a proces sor 7 and a data recorder 8 in the form of the digital signal extended to L bits to be stored with operation. In such a way, the converter 1 leaves L bits of the result obtained through addition and division by the number of sample points. Thus the accuracy of the converter 1 can be improved up to 2M<->L.
