Abstract:
Embodiments of the disclosure are drawn to apparatuses and methods for controlling refresh operations. Responsive to a refresh command, or one or more pumps generated responsive to the refresh command, different banks of a memory array may perform different types of refresh operations for a pump. In some examples, the type of refresh operation performed by a bank may vary from pump to pump of a refresh operation.
Abstract:
Apparatuses for timing control in a write path are disclosed. An example apparatus includes: a clock input circuit that receives a clock signal and provides an internal clock signal; a command decoder that receives command signals and the internal clock signal, and provides an active write command signal when the command signals indicates a write operation; a write latency shifter that receives the write command signal, a latency value and a WICA value, adjusts timing of the write command signal responsive to the latency value and the WICA value, and provides a shifted write command signal; and a write DLL including a delay line that receives the shifted write command signal and provides a delayed write command signal. The write DLL provides the WICA value to set a propagation time from the clock input circuit to the write DLL to be a multiple of a period of the clock signal.
Abstract:
A semiconductor memory disclosed in this disclosure includes first and second memory cell arrays, a first main data line that transfers the read data read from the first memory cell array, a second main data line that transfers the read data read from the second memory cell array, a main amplifier coupled to the second main data line, and a repeater circuit coupled to the first main data line and the second main data line.
