SEMICONDUCTOR MEMORY DEVICE AND SYSTEM USING SEMICONDUCTOR MEMORY DEVICE |
摘要 |
A semiconductor memory device comprises a RAM (Random Access Memory), an ODT (On-Die Termination) circuits and a JTAG (Joint Test Action Group) circuit. The RAM is connected to a data input-output port. The ODT circuit is provided between the data input-output port and a termination port. The JTAG circuit controls the ODT circuit in response to an instruction such that the data input-output port and the termination port are electrically connected with each other.
