Abstract
Abstract A self latching input buffer is disclosed which includes an address input buffer which is responsive to a first clock signal so as to produce an output signal. data in the input buffer is latched in connection with the receipt of a second clock signal which is produced by a detector which is responsive to the output signal.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
99 words
A random access memory self-latching input buffer circuit comprising: a clock operable to produce a first clock signal; an input buffer operable to receive the input of a row address from an integrated circuit bond pad in connection with the receipt of said first clock signal; and a detector operable to receive an output from said input buffer, aid detector being further operable to produce a second clock signal in connection with the receipt of said input buffer output said input buffer being operable to latch said row address in connection with the receipt of said second clock signal.
Claim 2
Dependent Claim
99 words
A random access memory self-latching input buffer circuit comprising: a clock operable to produce a first clock signal; an input buffer operable to receive the input of a row address from an integrated circuit bond pad in connection with the receipt of said first clock signal; and a detector operable to receive an output from said input buffer, aid detector being further operable to produce a second clock signal in connection with the receipt of said input buffer output said input buffer being operable to latch said row address in connection with the receipt of said second clock signal.
Claim 3
Dependent Claim
99 words
A random access memory self-latching input buffer circuit comprising: a clock operable to produce a first clock signal; an input buffer operable to receive the input of a column address from an integrated circuit bond pad in connection with the receipt of said first clock signal; and a detector operable to receive an output from said input buffer, said detector being further operable to produce a second clock signal in connection with the receipt of said input buffer output, said input buffer being operable to latch said column address in connection with the receipt of said second clock signal.
Claim 4
Dependent Claim
99 words
A random access memory self-latching input buffer circuit comprising: a clock operable to produce a first clock signal; an input buffer operable to receive the input of a column address from an integrated circuit bond pad in connection with the receipt of said first clock signal; and a detector operable to receive an output from said input buffer, said detector being further operable to produce a second clock signal in connection with the receipt of said input buffer output, said input buffer being operable to latch said column address in connection with the receipt of said second clock signal.
