Abstract
An encoding system may be provided. The encoding system may comprise a first stage and a second stage. The first stage may be configured to receive a first input, decode the first input, and produce a first output comprising the decoded first input. The second stage may be configured to receive a second input, receive the first output from the first stage, and convert the first input and the second input from a first coding system to a second coding system based on the second input and the first output. The second stage may produce a second output comprising the converted first input and the converted second input.
Claims20
An apparatus comprising:
- a first stage comprising a 7:1 decoder, wherein the 7:1 decoder decodes a first input to produce a first output;
- and
- a second stage configured to;
- receive the first output from the first stage,
- receive a second input,
- convert the first output and the second input from a first code to a second code based on the second input and the first output, and
- a first plurality of two input port AND gates, each one of the first plurality of two input port AND gates having a first input port respectively connected to one of seven output nodes of the 7:1 decoder and a second input port connected to an inverse of an input bit.
A method comprising:
- producing, by a first stage, a first output comprising a decoded first input, wherein the first stage comprises a 7:1 decoder;
- receiving, by a second stage, the first output from the first stage;
- receiving, by a second stage, a second input;
- and
- converting, by the second stage, the first output and the second input from a first code to a second code based on the second input and the first output, wherein the second stage comprises a first plurality of two input port AND gates, each one of the first plurality of two input port AND gates having a first input port respectively connected to one of seven output nodes of the 7:1 decoder and a second input port connected to an inverse of an input bit.
An apparatus configured to:
- receive a first input;
- produce a first output from the first input by decoding the first input using a 7:1 decoder of a first stage;
- receive a second input;
- convert the first output and the second input from a first code to a second code based on the second input and the first output at a second stage, wherein the second stage comprises a first plurality of two input port AND gates, each one of the first plurality of two input port AND gates having a first input port respectively connected to one of seven output nodes of the 7:1 decoder and a second input port connected to an inverse of an input bit;
- and
- provide the converted first output and second input to a trimming function of a Sense Amplifier.
