Semiconductor apparatus and semiconductor system including the same

摘要

A semiconductor apparatus includes a plurality of unit memory blocks and a plurality of sense amplifier arrays configured to be shared with two or more unit memory blocks among the plurality of unit memory blocks, and amplify data of the unit memory blocks. When a unit memory block corresponding to an external address and a unit memory block corresponding to a refresh address among the plurality of unit memory blocks are coupled in common to one of the plurality of sense simplifier arrays, the semiconductor apparatus stores the refresh address and executes a normal operation command corresponding to the external address.

主权项

1. A semiconductor apparatus comprising:
a plurality of unit memory blocks; a plurality of sense amplifier arrays configured to be shared with two or more unit memory blocks among the plurality of unit memory blocks and amplify data of the unit memory blocks; a refresh counter configured to generate a refresh address, and fix a value of the refresh address according to an activation of a refresh control signal; and a refresh control circuit configured to store the refresh address, execute a normal operation command on the unit memory block corresponding to an external address, and activate the refresh control signal, in response to a unit memory block corresponding to the external address and a unit memory block corresponding to a refresh address among the plurality of unit memory blocks being coupled in common to one of the plurality of sense amplifier arrays.
