Embodiment Construction

[0020] Specific details are set forth below in order to provide a thorough understanding of examples of the invention. It will be apparent, however, to one skilled in the art that examples of the invention may be practiced without these specific details. Furthermore, specific examples of the invention described herein should not be construed to limit the scope of the invention to these specific examples. In other instances, well-known circuits, control signals, timing protocols and software operations have not been shown in detail in order not to unnecessarily obscure the present invention. Additionally, terms such as "coupled" mean that two components may be directly or indirectly electrically coupled. "Indirectly coupled" may imply that two components are coupled through one or more intermediate components.

Abstract

Apparatuses and methods including memory commands for semiconductor memories are described. An example method includes receiving a data clock signal responsive to receiving a timing command, performing an access operation responsive to receiving an access command associated with the timing command, providing an access data clock signal based on the data clock signal, and providing an access data clock signal based on the data clock signal. The access command may be separated in time from the associated timing command by at least one clock cycle of a system clock signal. In some examples, the access command may precede the associated timing command or may follow the associated timing command. In some examples, the access command may immediately follow or precede the associated timing command.

Description

Background technique [0001] Semiconductor memory is used in many electronic systems to store data that can be retrieved at a later time. With the increasing demand for faster electronic systems that have greater computing power and consume less power, semiconductor memories that can access faster, store more data and use less power have been continuously developed to meet changing needs . Part of the development includes establishing new specifications for controlling and accessing semiconductor memory, where generation-by-generation changes in the specification aim to improve memory performance in electronic systems. [0002] Semiconductor memory is generally controlled by providing the memory with command signals, address signals, and clock signals. Various signals may be provided by, for example, a memory controller. The command signals may control the semiconductor memory to perform various memory operations, such as read operations for retrieving data from the memory a...
