Reconfigurable logic architecture

摘要

According to one general aspect, an apparatus may include a plurality of stacked integrated circuit dies. The dies may include a memory cell die configured to store data in a random access fashion. The dies may also include a look-up table die comprising a random access memory array that, in turn, includes a reconfigurable look-up table. The reconfigurable look-up table may be configured to perform a logic function. The reconfigurable look-up table may include a plurality of random access memory cells configured to store a look-up table to perform a logic function, and a local row decoder configured to activate one or more rows of memory cells based upon a set of input signals. The look-up table stored in the plurality of memory cells may be configured to be dynamically altered via a memory write operation to the random access memory array.

1. An apparatus comprising:
a plurality of stacked integrated circuit dies comprising:
a memory cell die configured to store data in a random access fashion; anda look-up table die comprising a random access memory array that comprises a reconfigurable look-up table configured to perform a logic function and comprises:
a plurality of random access memory cells configured to store a look-up table to perform a logic function,a local row decoder configured to activate one or more rows of memory cells based upon a set of input signalsa local line selector configured to select a sub-set of values stored in the activated one or more rows of memory and output the selected values as the output of the look-up table, wherein the values, as output, are the same as the values, as stored, andwherein the look-up table stored in the plurality of memory cells is configured to be dynamically altered via a memory write operation to the random access memory array.
