Title: Sound recording and reproducing device
Inventor: YANAGI HARUYUKI
IPC: G11C27/00
Filed: 1988-10-14
Abstract: PURPOSE:To hold secrecy by reproducing the recorded sound of a specified channel only when a personal identification number which is inputted at the time of reproduction matches a registered personal identification number. CONSTITUTION:A control part 4 is provided with a means 16 for inputting channel specification and the number which needs to be held secret and the number registering means 10. Then only when the personal identification number which is inputted at the time of the reproduction matches the registered password number, the recorded sound of the specified channel is reproduced. At this time, when the number does not match the registered one, the sound is not reproduced and the reproducing function is ended. Consequently, the contents of sound recording are not easily reproduced by a third party who does not know the personal identification number and the secrecy is maintained.

Title: Ic memory card
Inventor: SAITO OSAMU
IPC: G11C29/00
Filed: 1990-09-28
Abstract: PURPOSE:To protect fixed information by detecting the access to the fixed area of a storage part, masking a writing control signal transmitted from the host side and inhibiting the write-in of data to the storage part. CONSTITUTION:When a bus clock BCK4 is transmitted from the host side, a read/write controller 202 transmits a writing approval signal WE. At this time, when an address to be accessed is in the range of '000000' to '0000FF' of the fixed area, a detection signal Det is supplied to an AND gate 300 of the controller 202. Accordingly, the signal WE is masked with the signal Det and not transmitted, so the data supplied to a main memory 10 is not written in. When the write-in of the data is completed, the host returns an address data identification signal, the inverse of A/D to a LOW level and proceeds to the next processing. At this time, an address decoder 206 detects the fall of a signal A/D and stops generating the signal Det. Thus, when the fixed information is erroneously accessed, the fixed information can be protected.
