摘要:
A memory device in which both DRAM and phase-change memory (PCRAM) are mounted is provided with a DRAM bit line, a PCRAM bit line or a PCRAM source line formed on an conductive layer shared with the DRAM bit line, and a sense amplifier connected between the DRAM bit line and the PCRAM bit line. The memory device further has a capacitive element disposed on the upper layer of the DRAM bit line, and a phase-change element disposed on the upper layer of the PCRAM bit line. The lower electrode of the capacitive element and the lower electrode of the phase-change memory element are formed on the shared conductive layer.
摘要:
A phase-change memory device includes a plurality of bit lines extending in a row direction, a plurality of selection lines extending in a column direction, and an array of memory cells each disposed at one of intersections between the bit lines and selection lines. Each memory cell includes a chalcogenide element and a diode connected in series, and an n-type contact layer underlying the n-type layer of the diode. Adjacent two of memory cells share a common bit-line contact plug connecting the n-type contact layers and the bit line.

摘要:
Disclosed is a semiconductor storage apparatus in which two sorts of memories, that is, a volatile memory and a non-volatile memory, are mounted on one chip. Data of a DRAM memory array are saved in a corresponding area of a non-volatile memory before entry to a data retention mode or before power down and data is transferred from the area of the non-volatile memory to the DRAM memory array in exiting from the data retention mode or power up. Normal read/write access is made to the DRAM memory array, while data retention is in an area of the non-volatile memory.

摘要:
In a process for manufacturing a semiconductor integrated circuit device having a MISFET, in order that a shallow junction between the source/drain of the MISFET and a semiconductor substrate may be realized by reducing the number of heat treatment steps, all conductive films to be deposited on the semiconductor substrate are deposited at a temperature of 500° C. or lower at a step after the MISFET has been formed. Moreover, all insulating films to be deposited over the semiconductor substrate are deposited at a temperature of 500° C. or lower at a step after the MISFET has been formed.
