Configurable link interfaces for a memory device

An apparatus, comprising:

• a memory array comprising a plurality of memory cells arranged as a plurality of rows and a plurality of columns;
• a read circuit configured to read, from the memory array, a memory word comprising bits arranged according to an order of the plurality of columns;
• a data channel interface comprising a plurality of pins configured to convey the bits of the memory word, wherein the plurality of pins are grouped into a plurality of groups of adjacent pins;
• and
• a plurality of multiplexers between the read circuit and the data channel interface, the plurality of multiplexers configured to serialize, for each group of the plurality of groups, a first subset of multiple bits of the memory word to a first pin and a second subset of the multiple bits of the memory word to a second pin, wherein the first subset of the multiple bits and the second subset of the multiple bits comprise interleaved subsets of bits of the memory word according to the order of the bits of the memory word.

An apparatus, comprising:

• a memory array comprising a plurality of memory cells;
• a plurality of latches having respective data outputs coupled with the memory array and configured to output logic state information for writing to the memory array, each of the plurality of latches having a control input;
• a data channel interface comprising a plurality of pins configured to convey the logic state information;
• and
• a plurality of nodes configured to support a first mapping between the data channel interface and the plurality of latches and a second mapping between the data channel interface and the plurality of latches, wherein:
• the first mapping maps the plurality of latches with a first quantity of the plurality of pins, and maps the control inputs for the plurality of latches to one or more first clock signals associated with input of the logic state information according to a first clock rate;
• and
• the second mapping maps the plurality of latches with a second quantity of the plurality of pins that is different than the first quantity, and maps the control inputs for the plurality of latches to one or more second clock signals associated with input of the logic state information according to a second clock rate that is different than the first clock rate.

An apparatus, comprising:

• a memory array comprising a plurality of memory cells arranged as a plurality of rows and a plurality of columns of memory cells;
• a write circuit configured to write a memory word to the memory array, wherein bits of the memory word are arranged according to an order of the plurality of columns;
• a data channel interface comprising a plurality of pins configured to receive the bits of the memory word, wherein the plurality of pins are grouped into a plurality of groups of adjacent pins;
• and
• a plurality of demultiplexers between the data channel interface and the write circuit, the plurality of demultiplexers configured to deserialize, for each group of the plurality of groups, a first subset of multiple bits of the memory word from a first pin and a second subset of the multiple bits of the memory word from a second pin, wherein the first subset of the multiple bits and the second subset of the multiple bits comprise interleaved subsets of bits of the memory word according to the order of the bits of the memory word.
