Abstract
Provided are a semiconductor device and a semiconductor system. A semiconductor device includes a memory cell array; a standard cell region in which first type standard cells implemented to perform a first operation for accessing the memory cell array and second type standard cells performing the first operation and having performance characteristics different from performance characteristics of the first type standard cells are arranged; and a ROM including a program that performs place and route for the standard cells arranged in the standard cell region.
Claims10
An integrated circuit device, comprising:
- a memory cell array in a semiconductor substrate;
- and
- user-programmable standard cell logic electrically coupled to said memory cell array, said user-programmable standard cell logic comprising a first plurality of standard cells configured to support first write and/or first read operations in said memory cell array, which are selected based on a first program state of said user-programmable standard cell logic, and a second plurality of standard cells configured to support second write and/or second read operations in said memory cell array, which are selected based on a second program state of said user-programmable standard cell logic, said second write and/or second read operations having different performance characteristics relative to performance characteristics associated with the first write and/or first read operations.
An integrated circuit device, comprising:
- a memory cell array in a semiconductor substrate;
- standard cell logic electrically coupled to said memory cell array, said standard cell logic comprising a first plurality of standard cells configured to support first write and/or first read operations in said memory cell array and a second plurality of standard cells configured to support second write and/or second read operations in said memory cell array having different performance characteristics relative to performance characteristics associated with the first write and/or first read operations;
- a programmable read-only memory (PROM) electrically coupled to said standard cell logic;
- input/output (I/O) pins;
- and
- first I/O standard cells in said standard cell logic, said first I/O standard cells configured to establish a first number of the I/O pins as active and a second number of the I/O pins as inactive, in accordance with I/O pin programming information contained in said PROM.
An integrated circuit device, comprising:
