Single READ-THEN-CLEAR Command for DRAM in Printing Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printing systems consume significant computational resources and time due to the need for separate series of commands for reading data from and clearing dynamic random access memory (DRAM) cells, which can be inefficient in large-scale printing processes.
Innovation Solution
Implementing a single READ-THEN-CLEAR command that allows for reading data from and subsequently clearing DRAM cells with a single command, reducing the number of issued commands and the quantity of write data required, thereby optimizing the printing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate READ and WRITE commands are used to clear DRAM cells, then data can be read and cleared, but the number of commands increases and computational resources are consumed
Solution Approach 1:
The patent combines the READ and WRITE operations into a single READ-THEN-CLEAR command. When this command is executed, the DRAM device reads the data from the specified memory location and automatically clears it, eliminating the need for separate READ and WRITE commands. This merging of operations directly reduces the number of commands issued and the computational resources required.
Solution Approach 2:
The READ-THEN-CLEAR command serves multiple functions simultaneously: it reads data from DRAM cells, outputs the read data, and clears the memory cells for reuse. This multi-functional command structure allows a single operation to accomplish what previously required multiple separate commands, thereby reducing system complexity and resource consumption.
2Reliability
If separate READ and WRITE commands are used, then data operations can be completed, but time is consumed due to multiple command sequences
Solution Approach 1:
By merging the READ and WRITE operations into a single READ-THEN-CLEAR command, the patent eliminates the time required to issue, process, and execute separate commands. The single command is processed in one operation sequence, reducing the total time spent on memory management operations during printing processes.
Solution Approach 2:
The READ-THEN-CLEAR command performs the clearing action immediately after reading, within the same command execution cycle. This preliminary integration of the clear operation eliminates the need to wait for a separate WRITE command to be processed, thereby reducing the overall time required for the complete read-and-clear operation.
3Reliability
If separate READ and WRITE commands are used, then data can be read and cleared, but computational resources are significantly consumed
Solution Approach 1:
The patent merges two computationally intensive operations (READ and WRITE) into a single READ-THEN-CLEAR command. This reduces the number of command processing cycles required, thereby decreasing the computational resources and energy consumed by the DRAM controller and associated processing units during printing operations.
Solution Approach 2:
The READ-THEN-CLEAR command performs multiple functions (reading data and clearing memory) in a single operation, reducing the overall computational workload. This multi-functional approach minimizes the number of processing steps required, thereby conserving computational resources and reducing energy consumption in the printing system.
Data Source
AI summary
A method includes receiving, at a dynamic random access memory (DRAM) device, a single READ-THEN-CLEAR command. The single READ-THEN-CLEAR command has a column address of a column in an array of memory cells. Particular data content is stored in memory cells associated with the column address. The method also includes, in response to receiving the single READ-THEN-CLEAR command, reading the particular data content and clearing the particular data content after reading the particular data content.
