A semiconductor memory device included memory cells each including two PNPN cells cross-coupled with each other, the PNPN cells each including a load transistor and a multi-emitter transistor, the multi-emitter transistor comprising a read/write transistor and a data holding transistor. The read/write transistor has means for decreasing the current amplification factor of the read/write transistor when it operates inversely, whereby the operating speed of the device is improved. |
