Abstract:
The back side of a strip substrate with plural semiconductor chips mounted thereon is vacuum-chucked to a lower mold half of a mold, and in this state the plural semiconductor chips are sealed with resin simultaneously to form a seal member. Thereafter, the strip substrate and the seal member are released from the mold and are cut into plural semiconductor devices. The semiconductor devices thus obtained are improved in their mounting reliability.
Abstract:
There is provided a method of programming a non-volatile memory which can solve the problem of the data write system of the existing flash memory that a load capacitance of bit lines becomes large, the time required by the bit lines to reach the predetermined potential becomes longer, thereby the time required for data write operation becomes longer and power consumption also becomes large because the more the memory capacitance of memory array increases, the longer the length of bit lines becomes and the more the number of bit lines increases. In the non-volatile memory of the invention comprising the AND type memory array in which a plurality of memory cells are connected in parallel between the local bit lines and local drain lines, the local drain lines are precharged by supplying thereto a comparatively higher voltage from the common drain line side (opposite side of the main bit lines), the main bit lines are selectively precharged by applying thereto the voltage of 0V or a comparatively small voltage depending on the write data and thereafter a drain current is applied only to the selected memory cells to which data is written by applying the write voltage to the word lines in order to implant the hot electrons to the floating gate.
Abstract:
The present invention provides a memory system which contributes to improvement in efficiency of a data process accompanying a memory access. A memory system has a rewritable nonvolatile memory, a buffer memory, and a controller. The controller controls, in response to an access request from an external apparatus, first data transfer between the controller and the external apparatus, second data transfer between the controller and the nonvolatile memory, and third data transfer between the controller and the buffer memory, controls transfer from the controller to the buffer memory in the third data transfer and transfer from the buffer memory to the controller in a time sharing manner, and enables the first data transfer or the second data transfer to be performed in parallel with the transfer carried out in the time sharing manner.
Abstract:
It is an object of the invention to provide a circuit configuration wherein a decoder control signal null2 is rendered unnecessary between an address buffer control signal null1 and the decoder control signal null2, thereby implementing speed-up in operation of a decoder circuit. The object is attained by adoption of a configuration wherein a buffer is integrated with a decoder, so that an output current path of transistors making up the address buffer, and that of transistors making up the decoder are connected with each other in series, thereby forming an output current path of decoder output. With the invention, speed-up in operation, lower power consumption, and higher cycle, of decoder circuits, can be achieved. Further, in the case of using the decoder circuits in a semiconductor memory, it is possible to achieve shortening of access time, lower power consumption, and higher cycle with reference to the semiconductor memory.

Abstract in simplified Chinese:本发明提供一种半导体集成电路设备,可以降低将箝位电路堆栈两层时的阻抗。
在高电位侧电源(VDD)与低电位侧电源(VSS)间配设,分别用以将非所希望位准的电压加以箝位的第1箝位电路(10),及纵方向堆栈其上的第2箝位电路(20),纵方向堆栈第1箝位电路(10)与第2箝位电路(20)而形成的中间节点(100),则结合在内部电路用电源(VDDi)。因原来配设在内部电路的电容器与第1箝位电路配置成并联状态,因此,由于有此电容器的存在,阻抗降低,流动于芯片内的过电流造成的电位差变小。借此,可以使流动于芯片内的过电流造成的电位差变小,允许更大的过电流,以提高静电耐压。

Abstract in simplified Chinese:本发明的课题在于:降低因记忆卡之输入端子的提升电阻所造成的电力耗损,以达成防止因记忆卡之输入端子的提升电阻与主机设备之下拉电阻间的关系所形成的错误动作。为达成上述课题,本案的记忆卡(1)具有连接于提升电阻的选择端子(P0)。选择端子的提升电阻,可在根据选择端子的输入来判定卡片模式的判定时机之前选择较小的阻抗值,并在前述判定模式之后恢复成原先的阻抗值。较大的阻抗值可降低选择端子之提升电阻所耗损的泄漏电流。虽然当下拉电阻(32)被连接于安装有记忆卡之记忆卡主机的端子时,一旦提升阻抗值过大,将会受到因下拉电阻所形成之导入现象的影响,但只要于模式判定时降低选择端子的提升阻抗,便可避免受到因下拉电阻之电位导入的不良影响。
