Patent number: 7201581Abstract: A multifunction IC card (MFC) has compatibility with a multimedia card, an SD card, etc. in that connector terminals (#1 through #13) are disposed on a card substrate (1) in two rows in a zigzag fashion, and realizes multifunction facilities in that a memory card unit (3) and an SIM (Subscriber Identity Module) card unit (4) are respectively connected and mounted to predetermined terminals of the connector terminals (#1 through #13). The memory card unit (3) and the SIM card unit (4) are respectively separately provided with areas for storing secret codes for security. Thus, one IC card is capable of implementing multifunction facilities different in security level. Owing to the adoption of a plural-column layout corresponding to a form typified by the zigzag fashion in an array of the connector terminals, a relatively simple structure can be adopted in a card slot.Type: GrantFiled: May 3, 2005Date of Patent: April 10, 2007Assignees: Renesas Technology Corp., Hitachi ULSI Systems Co., Ltd.Inventors: Hirotaka Nishizawa, Haruji Ishihara, Atsushi Shiraishi, Yosuke Yukawa

Patent number: 6725322Abstract: Blocks and clusters are brought to correspondence thereby to erase blocks of memory area efficiently. A flash memory has its physical addresses partitioned from address 0h sequentially into blocks each having eight sectors. The data area of logical address starts at address 4Dh, which is set to the starting physical address 50h of the block which is close to the top of data area, and the data area is set sequentially to the following physical addresses. The remaining logical addresses 3D7Dh-3D7Fh are brought back to the top of physical address and set to physical addresses 0h-2h. Consequently, clusters (a cluster has 4 k bytes or 2 k bytes) of data sent from a host unit correspond to blocks of physical addresses, enabling block erasure of the flash memory, whereby the number of times of erasing operation at data writing can be reduced significantly.Type: GrantFiled: August 21, 2001Date of Patent: April 20, 2004Assignees: Renesas Technology Corp., Hitachi ULSI Systems Co., Ltd.Inventors: Atsushi Shiraishi, Manabu Inoue, Shigemasa Shiota, Yosuke Yukawa, Yuichiro Onuki, Takeshi Suzuki, Kenzo Matsumura
