description
The SMJ4C1024 is a 1048576-bit DRAM organized as 1048576 words of one bit each. It employs technology
for high performance, reliability, and low power at a low cost.
This device features maximum RAS access times of 80 ns, 100 ns, 120 ns, and 150 ns. Maximum power
dissipation is as low as 305 mW operating and 16.5 mW standby on 150-ns devices.

peaks are typIcally 140 mA and a –1 V input voltage undershoot can be tolerated, minimizing system noise.
All inputs and outputs, including clocks, are compatible with series 54 TTL. All addresses and data-in lines are
latched on-chip to simplify system design. Data out is unlatched to allow greater system flexibility.
The SMJ4C1024 is offered in an 18-pin ceramic dual-in-line package (JD suffix), a 20/26-terminal leadless
ceramic carrier package (FQ/HL suffixes), a 20/26-pin J-leaded carrier package (HJ suffix), a 20-pin flatpack
(HK suffix), and a 20-pin ceramic zig-zag in-line package (SV suffix). They are characterized for operation from
