Abstract
Examples described include dynamic data caches (DDCs), decoders and decoding methods that may fit into a smaller width area. The DDCs, decoders and decoding method may be used in flash memory devices. A single column select line may be provided to select a plurality of cached bytes, while a second select line selects a byte of the selected plurality. The column select line may be routed parallel to bit lines carrying data, while the second select line may be routed perpendicular to the bit lines.
Claims10
A dynamic data cache region comprising:
- a plurality of dynamic data caches, each configured to store a plurality of bytes of data;
- a plurality of bit lines, wherein the plurality of bit lines are configured to provide the plurality of bytes of data to the plurality of dynamic data caches;
- a first select line configured to select a group of the plurality of bytes of data;
- and
- a second select line configured to select a byte within the group.
2 more elements
A dynamic data cache system comprising:
- a plurality of dynamic data caches, wherein each of the dynamic data caches includes storage for a first plurality of bytes and a second plurality of bytes, wherein a count of bytes of the first plurality of bytes is equal to a count of bytes of the second plurality of bytes;
- a first select line configured to select the first plurality of bytes of the plurality of dynamic data caches;
- a second select line configured to select the second plurality of bytes of the plurality of dynamic data caches;
- a first decoder coupled to the first select line and configured to decode a select signal and provide the decoded select signal to the first select line;
- and
- a second decoder coupled to the second select line and configured to decode the select signal and provide the decoded select signal to the second select line.
