Abstract
A switched current memory circuit has an input to which an input current (i) is applied and which is connected via a switch (S1) to the drain electrode of a memory transistor (M). A second switch (S3) is connected between the memory circuit input and the source electrode of a grounded gate transistor (G) whose drain electrode is connected to the gate electrode of the memory transistor (M). The drain electrode of the memory transistor (M) is connected via switch (S2) to an output at which an output current (i.sub.o) is produced. The second switch (S3) provides zero-voltage switching which reduces the effects of charge injection on the current stored.
