Semiconductor memory having non-standard form factor

摘要

A semiconductor memory chip including error correction circuitry configured to receive data words from an external device, each data word comprising a binary number of data bits, and configured to error encode each data word to form a corresponding coded word comprising a non-binary number of data bits including the data bits of the data word and a plurality of error correction code bits. At least one memory cell array is configured to receive and store the coded word and partitioned based on the non-binary number of bits of the coded word so as to have a non-binary number of wordlines and provide the memory chip with an aspect ratio other than a 2:1 aspect ratio.

1. A semiconductor memory chip comprising:
logic circuitry employing a binary external page size to send/receive data bits to/from external devices, the binary external page size comprising a binary number of data bits; error correction logic configured encode one or more groups of data bits of a page of data received from the logic circuitry to form coded words that together form a non-binary internal page size comprising a non-binary number of data bits, including the data bits of the one or more groups of data bits and error correction bits; and a plurality of memory cell arrays configured to store the coded words, each having a non-binary number of wordlines based on the non-binary internal page size arranged to provide the memory cell block with an aspect ratio of other than 2:1.
