    Abstract: PROBLEM TO BE SOLVED: To supply power required for activating a memory cell field immediately with simple structure via a short power feed line by setting a first electrical connection line to a high ohmic state and a second electrical connection line to a low ohmic state. SOLUTION: A semiconductor integrated memory device consists of memory cell fields 1-8, and the cell fields 1-8 are arranged in a line and are interconnected via power feed lines 11 and 12 with low ohmic at both sides. Also, a power feed line 13 with low ohmic is connected to the surrounding of each of memory cell fields 1-8. Then, a sense amplifier 5 exists at regions among the memory cell fields 1-8. The power feed lines 11, 12, and 13 with low ohmic form a low-ohmic power supply circuit network, and the circuit network is connected to a power supply generator 9 via a high-ohmic line 10.

    Abstract: PROBLEM TO BE SOLVED: To realize a method for a self-test of constitution elements of a semiconductor memory.
    SOLUTION: This invention relates to a method for testing constitution elements of a semiconductor memory. Data is accumulated in a bank having matrix structure, and the matrix structure is provided with rows and columns to which addresses can be specified. In this method, an error address is transmitted for an external test layer in a compressed form from an error position in a bank. Rows or columns are divided into regions, error caused in each region are counted for each row or column, the number of errors in each region are compared with a threshold value for each row or column, and the comparison result is transmitted to a test device with an error address as additional information for each row or column.

    Abstract: PROBLEM TO BE SOLVED: To obtain a circuit device that can read stored information while leaving the stored information as it is, furthermore, examines based on the information whether information that should have been originally assigned to a volatile storage element can be restored from the state of an assigned programmable element or not, and inspects the state of a storage. SOLUTION: The circuit device is equipped with one programmable element 2 and a storage 10 with a volatile storage element 1. In order to store the state of the programmable element, the programmable element 2 is connected to the volatile storage element 1 for each storage 10. Each storage 10 has at least one of output sides Q1 and Q2 for inspecting each state of the programmable element 2 and the volatile storage element 1. In the storage 10, at the time when the state of the programmable element 2 and the volatile storage element 1 is outputted via a selection circuit, an address can be individually specified. Information stored into the volatile storage element remains as it is saved.

    Abstract: PROBLEM TO BE SOLVED: To prevent surely rapid deterioration process of fuse/anti-fuse and unexpected burnout of fuse/anti-fuse being never burned out hitherto in reading out fuse/anti-fuse of a semiconductor memory assembly such as especially a DRAM. SOLUTION: In reading out of fuse/anti-fuse, voltage Vb1h deciding a high potential of a bit line BL of a memory cell array 6 is used instead of internal voltage Vint being general hitherto. The voltage Vb1h is reduced for the internal voltage Vint, especially, it is preferable that voltage Vb1h is reduced by almost 20% to 30% for the internal voltage Vint.

    Abstract: PROBLEM TO BE SOLVED: To allow a programmable element to be programmed with a high voltage and allow an area of a circuit element of a readout circuit to be saved by connecting a second terminal of the programmable element, to which a first terminal of a protective circuit is connected, to an input side of the readout circuit and by limiting a voltage at the second terminal. SOLUTION: A terminal al of a protective circuit 1 is connected to a terminal AF of a programmable element F, while a terminal a2 is connected to a terminal EA on an input side of a readout circuit A. During a programming process of the programming element F, an electrical potential V1 has a positive burn- voltage value. When a switchable element is switched so as to be conducting, the programmable element F is transferred into a low ohm condition and an electrical potential at a node K increases to the burn-voltage value. At this time, an electrical potential at a node N does not increase to exceed a sum of an electrical potential V3 corresponding to a normal positive operating voltage and a forward voltage of a diode D.
