Abstract
Apparatuses and methods for providing activation timings of sense amplifiers in a semiconductor device are described. An example apparatus includes: a first memory bank including at least one first sense amplifier that is enabled responsive to a first activation signal; a second memory bank including at least one second sense amplifier that is enabled responsive to a second activation signal; and a control circuit that receives a control signal. The control circuit includes a delay circuit that provides a delayed control signal by delaying the control signal, a first sense amplifier control circuit coupled to the first delay circuit and provides the first activation signal respective to the delayed control signal when the first memory bank is designated, and a second sense amplifier control circuit coupled to the delay circuit and provides the second activation signal respective to the delayed control signal when the second memory bank is designated.
