Abstract: PURPOSE:To simplify operation, by specifying a memory cell to be selected belongs to the positive or negative bit lines of differential sense amplifiers from an address signal, and inverting the logical level of external data according to the signal and making its level coincident with a storage potential level. CONSTITUTION:A memory matrix is divided into parts M and -M with sense amplifiers SA0-SA127 between; the part M is connected to word lines W0-W63, and bit lines B0-B127 and the part -M is connected to word lines W64-W127, and bit lines -B0--B127.

Title: Carrier sense circuit
Inventor: MANZEN YOSHIHISA
IPC: H04B17/318
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To minimize the delay of the carrier sense output by detecting the input of a carrier signal via a carrier sense device and connecting a capacitor where the reference voltage is previously charged by a switch changeover device to an RSSI part in a carrier sense mode. SOLUTION: If the steady RSSI voltage VL is larger than the reference voltage VR, the output of an IF amplifier 2 is generated with input of a carrier signal. A trigger circuit 13 outputs a pulse as a carrier sense signal. Receiving this pulse, a switch control circuit 14 switches a changeover switch 16 to the side (b) from the side (a). A comparator 12 compares the voltage VL with the voltage VR when a short time (t) passed after the changeover of the switch 16 and outputs the carrier sense signal. This output timing is almost equal to the input of the carrier signal and is minimized. If the carrier signal is inputted when the voltage VL is smaller than the voltage VR, the IF amplifier output is generated. Then the comparator 12 compares the voltage VL with the voltage VR when the time (t) passed after the changeover of the switch 16.  In such cases, no carrier sense signal is outputted since the voltage VL never exceeds the voltage VR.
