Abstract
Methods and systems for selectively compressing data lines of a memory device in selective compression circuitry. The selective compression circuitry receives multiple data lines and compression circuitry that selectively compresses inputs. The selective compression circuitry also includes control circuitry to receive data over via the data lines. The control circuitry, when in a compressed mode, transmits data from each of the data lines to the compression circuitry. Alternatively, in an uncompressed mode, the control circuitry transmits data from a first subset of the data lines to the compression circuitry while blocking data from a second subset of the data lines from being transmitted to the compression circuitry.
Claims21
A memory device, comprising:
- a plurality of data lines;
- compression circuitry configured to selectively compress inputs;
- and
- control circuitry configured to receive data over the plurality of data lines, and configured to:
- when in a compressed mode, transmit data from each data line of the plurality of data lines to the compression circuitry;
- and
- when in an uncompressed mode, transmit data from a first subset of data lines of the plurality of data lines to the compression circuitry while blocking data from a second subset of data lines of the plurality of data lines from being transmitted to the compression circuitry.
A memory device, comprising:
- a plurality of data lines;
- a plurality of compression channels each configured to selectively compress inputs received at the respective compression channel;
- a plurality of control channels each configured to:
- receive data over a subset of data lines the plurality of data lines;
- receive a plurality of control signals;
- and
- selectively transmit data from one data line of the plurality of data lines or from both data lines of the subset of data lines as the inputs to the respective compression channel;
- and
- selection circuitry configured to combine outputs from the plurality of compression channels to produce a single output.
Selective compression circuitry, comprising:
- a control channel configured to:
- receive control signals;
- receive a plurality of data signals;
- and
- select one or more data signals to transmit based at least in part on the control signals;
- and
- a compression channel configured to receive the transmitted one or more data signals, wherein the compression channel is configured to:
- pass the one or more data signals when only a single data signal is passed to the compression channel in the one or more data signals;
- and
- combine the one or more data signals when more than a single data signal is passed to the compression channel in the one or more data signals.
